It's not people finding him tasteless that caused this.. It's the guy who wrote it turning himself into the cops under the law that's there to protect from cyber bullying and trolling.. Sounds like he did it to protect himself from equally (or more) tasteless and irresponsible trolling.. All silliness that's got out of hand..

What are the cops to do when someone turns themself in (as the guy did from the article)?

From the article, the guy turned himself in, from the sound of it, most likely because he had threats against himself. It's unlikely the police would have even heard of this if he hadn't gone to the station and said he'd done something stupid. It had the benefit (to him) of exposing the threats against himself, which also fall under the anti-troll and cyber bullying laws, so the people who'd threatened him will also be lined up for a big slap on the wrist.

If this had been randomly picked up by a police trawl, I'd have been worried.. As it stands (someone turning himself in and admitting he'd be stupid, and asking for protection), it's looking like far less.. Good tabloid fodder.

Ok, so native Americans taking back America by armed force would be ok? Or areas of the world suddenly taking up arms and taking back areas around their border is suddenly ok (that's about the beginnings of world war 1 and 2).
The Falklands have been British for many generations (they've been British since 1833). The occupants are all British, and identify as being British. In votes, they chose to remain British, and actively oppose any attempt to make it otherwise. The UK was involved in negotiations to transfer the islands at Governmental level, but the now many-generations-established populace applied pressure to not allow this to happen.
The history is far more nebulous than "being owned by Argentina". If you apply proximity rules, then by your logic, Ireland should definitely be owned by England.

So, what you term "Evil" is actually supporting the wishes of a population that is well established (many generations over almost 200 years) who have lobbied hard to have their voices heard. These established occupants made it impossible to negotiate a transfer, so the only way to do it would be to evict them and force them off (which means you're pro forced resettlement of a population, which is really not a good thing).
The legal measures failed because the population of the affected area spoke their wishes.

So, not abiding by the established population's wishes, Argentina fell back to force, and sent in military to force the populace at gunpoint to claim what once was an unpopulated island (prior to England and France populating it back in the 1600's).

Have a good read of the history, and it turns out that Argentina has only very tenuous claim to the Islands.
Now, England has been allowing Ireland, Scotland and Wales to secede if they wish (i.e. the recent Scottish independence referendum). This is seen as a progressive measure.
If Argentina were to establish a claim on the Falklands, do you think they'd allow it to secede, despite the entirity of the population voting to leave? Would they hell. If they did, Falklands would secede at the first vote (they've made that plain), and would likely choose to join either England again as they historically have chosen to, or perhaps the EU.

So, no. What MT did in 1982 was exactly what she was supposed to do. Protiect British Citizens from invasion by foreigh force. Exactly what the island owners (the Falklanders, not Argentina) wished.

It's just mildly amusing that the state says "thou shalt not be sexist", and yet by using affirmative action is blatantly racist and sexist in a very strong way.

Just like teaching is systematically female. As is Nursing, and a whole load of other fields. When they put extra funding towards getting more men in teaching (especially primary), I'd say fair game for allowing targetting of women to male dominated fields. Lets start off with road construction gangs, sewer workers and general construction, where the female count is incredibly small (the most underrepresented fields).. Where are the cries that more women need to be in those fields?

No, people try very hard to make a better world. Simply admitting we're not in a perfect one isn't shrugging and doing nothing. We know there are bad people and sick people out there. Pretending otherwise is not a survival trait. Fear of everything is also not a great trait; there's a definite balance, and that's variable on location and company.

Was going to mod you insightful, but thought you may like a link to Channel 4's "Utopia" if you haven't heard of it, or watched it..

My diet is vegetarian. I only eat vegetarians. Mmmm.. Steak.

Ok, so they chose women who'd left the field completely. That means getting out full stop. You don't do that for career progression, you don't usually do that for more salary. You get out because it's not for you.
Now, if they'd gone and surveyed an equal number of women who chose to stay in the field as well, and an equal number of men who had left the field entirely and also ones who chose to stay, they'd at least be showing an attempt to remove bias. But no. They chose to skew the numbers completely and then write that it's all the fault of men (again).
I nearly got out of the field because the women in management above me didn't really understand how to run an enterprise class department, which did nasty things to my health.
I'm pretty sure that if you choose men who leave the field with women management as a bias adjuster you'd find a lot that just say "management often sucks". Gender isn't necessarily the decider. Hell, where I work, the women are often far more lewd and crude than us men (for the simple reason they can; if we crack those jokes, we stand a very big risk of being had up for sexual harrassment if the gal in question is having a bad day). Politics these days are hideously misandrist, yet nobody seems to give a damn about that.

A Utilite Pro which gives me all the grunt I need for an always on server, coupled to an external old DroboPro with 10TB of storage.

There's a reason I don't buy Gigabyte. Out of all the boards I've bought and systems I've built, Gigabyte have had the greatest chance of just plain not working, working poorly, or having some other annoyance that gets in the way.

In a discussion, the aim, for a debate on a subject, is to reach an objective approximation.
There's a world of difference between actually striving to get to the crux of a matter and saying "You suck.. So I'm not listening to what you say, because I'm right because I say I am, and you're all idiots for just believing me.".
Philosophy is the attempt to achieve rational objective approximations, and is at the heart of striving to get things better. Saying that nobody has the requirement to attempt to be better while discussing is merely an excuse for laziness and trolling. I know you don't mean it as that, and it's no slight, but that's the way it ends up.
Really, I thoroughly enjoy a discussion with someone who has a different viewpoint to me on something. It's rare I don't learn something from that. But these days, there's an awful lot of ad hominem attacks used in place of actually having an argument or point of view.
You may still wish to perceive something a particular way, but it helps to have your view widened by actually having someone else's well rationalised view on it as well..
