"Even the most cynical adjustment of the numbers still shows a majority."
Your fault is assuming the numbers were in any way legitimate in the first place, which given objective polls from only a few weeks before gave only 41% support for joining Russia there's a pretty strong suggestion it is not the case.
I just held a poll of all Crimeans and they actually said 100% that they don't want to be part of Russia, even if you adjust for a bit of normal statistical error there you can't manipulate it far enough to say I'm wrong.
See how that works? That's basically what Putin did in reverse, so congratulations on being one of his useful idiots. The simple fact is that there was supposedly an 82% turn out, despite the fact that at least 30% weren't even ethnic Russian and had no interest in Russia. The results Russia spat out just were not credible in the slightest, and that's before you factor in the 120%+ election turnout in Sevastapol where Russian troops who weren't even Ukrainian nationals voted. Yes, you read that right.
"There was no evidence that the people of Iraq or Afghanistan wanted to be liberated, yet the world is just peachy with that."
Amusingly, whilst I disagree with the Iraq war, that's simply not true. The people were extremely grateful for liberation in the aftermath, it was the failure to plan to build a working nation state that resulted in all the case. There was actually massive popular support for Saddam's rival, the UK/US just completely failed to fill the vacuum left by his departure leading to a brutal power struggle, that's what went wrong there. The same has happened in Libya and Egypt - the vast majority wanted liberation from their respective dictators, the problem is they also didn't want the chaos that followed but eventually did because they didn't plan for what happens afterwards.
Look, the whole Iraq war was wrong, and that's fine, I get it, you hate America and the UK and whoever else for what they did. But that doesn't magically make Russia not as bad, Russia is still just as bad, arguably worse - at least the UK and US always planned to pull out and eventually did, Russia just annexed the place and declared it there own. You cannot honestly criticise the West for what they did and then defence Russia's actions, that just makes you the worst kind of hypocrit. That just tells us you've no interest in the truth, or the facts, you just want an excuse to slag off the West and big up Russia and if that's what you want then fine, just at least have the fucking courage to say what you mean and believe - that you're pro-Russian, agree with Putin and hate the West. At least have the courtesy to cut the bullshit.
Cards on the table, I'm embarrassed by what my country did, I'm disgusted by what the US did, but I'm also appalled by what Russia is doing. The UK and US' stupidity doesn't make Russia an angel, it just makes it another asshole nation as well in carrying out actions equally as unacceptable as the 2003 Iraq invasion and subsequent occupation.
