I would never call him "evil" I have yet to meet or hear of someone who is "evil".
His opinions and ideals are self-concerned and short sighted and the results of them are a cruel and brutal and whatever positive thing he can plopp out of his mouth is covered and tainted by the rest of the ideological garbage that has passed through it.
He wants a nightwatch man society, thats fine (I don't agree with it and think its dumb but still). He slaps on a hope that it will cause unions to be disbanded through armed force - thats not fine.
He wants to cut all wellfare support, thats ok. Most liberterians have a grand idea that this will cause the economic playing field to level. He slap on the intend that the poor can starve for all he cares - thats not ok.
And these are just picks from the great basket of horrid shit thats flung itself out of his mouth.
He's not evil, evil is a metaphysical idea of some otherwordly cruelty beyond humanity. Something that drives someone to commit cruel acts for no reason. I've never seen that in a human. He's not stupid, he's spent years working the political landscape and building some kind of power base (I would not be surprised if he turns up for office at some point). He is just a person to whom an idea of the individual and its ideas so far outweighs society and its needs that no one but the strongest are allowed rights.
He's just an ideological part - but ideals and ideologies are the start and it was the start of so much horrible nonsense in the 90's.
