Sorry, but I simply don't believe you.
I couldn't give a flying fuck whether you believe me or not. I don't need a degree to see the problem with the OP, which you have singularly failed to refute, or even argue about.
For your information.
the idiotic declaration of war by Britain and France
Don't be silly. Hitler cannot possibly have been "surprised" by the declaration of war given that he was warned war would result from an invasion of Poland. Clearly he knew what the result of invading Poland would be. What the allies didn't know was the secret deal with the Soviets to split Poland in two, with the Russian invading from the East.
People like you want it both ways. You really get on my tits. All criticism and no solutions.
There are two levels of private here. There's keeping things private from potential employers, friends, family, associates and so on and there's keeping things private from the NSA, GCHQ, Chinese Government and so on. The average guy or girl has absolutely no hope of keeping their online dealings private from the latter. From the former, you don't so much keep them private as be a bit circumspect when making use of the internet, your mobile phone and so on.
So far over the last 10 years I've had 1 credit card attempted theft (tried to transfer £4,000 out of it, bank caught it as "suspect" so it didn't happen) and I've had 2 email accounts hacked and used to send spam. Of the latter, the problem was weak passwords. I now have a "system" for passwords and none are weak, but that doesn't mean the NSA and GCHQ can't still read them. I have no intention of fighting a room full of Mathematics PhDs for my data.
Even if you get the NSA to stop doing this through political action, the Chinese, Russians and so on will still be doing it.
