I bet the mindkilling predated UKIP's victory, and only afforded an impetus to action for those already mindkilled.

I'd agree, it has at most increased the mindkill.

Why do you find this surprising? That's the standard attack. It's simply background music.

"Amazed" was the wrong word, used in a sloppy rhetorical sense. 'Disappointed' might be better.

When does the opposition to the Left ever respond with a little tit for tat?

Well, of course UKIP didn't respond in kind, including when the prank escalated to sending blood and shit. And of course, it's UKIP who are the fascists, so let's hit them with sticks!

What he understands that you don't is that his enemies won't fight back. If your enemies are fundamentally pacifists toward your aggression, why ever stop?

Thing is, I do understand this, but maybe I've haven't fully internalised the fact an intelligent person can think that they are 'fighting the power' (he argues that UKIP are extremely similar to Nazis) while crushing anyone who dares to utter a contradictory opinion. I would say I can't understand this behaviour, but that would be purely rhetorical, because I do know what compartmentalisation is.

And when you have an iron grip on the moral high ground because anyone who disagrees with you is racist, then I suppose you can afford to defect constantly.
