I saw this and thought of Decency...
I've been discussing the meaning of 'Decency' (if any; I am at best agnostic about whether there any underlying credo exists) with Flying Rodent. I was looking for something else (the 1983 broadcast; the above is the 1987 one) but found this. Transcript from 1:25 for about a minute follows:
The good thing about extremism is that it makes you feel good! because it provides you with enemies.
Let me explain.
The great thing about having enemies is that you can pretend that all the badness in the whole world is in your enemies, and all the goodness in the whole world is in you.
Attractive isn't it?
If you have a lot of anger and resentment anyway and you therefore enjoy abusing people, you can pretend that you're only doing it because these enemies of yours are such very bad persons. And if it wasn't for them, you'd actually be good natured and courteous and rational all the time.
So if you want to feel good, become an extremist.
Prescient, I call that. Discuss.
