What made one conservative was the recognition of the human capacity for evil, for just plain screwing up. That was why the rules were important. Not because conservatives expected no one to break them. But because having rules that were respected made it harder for people to do so. Not many people would have the intellectual depth and the emotional courage to make the political journey that David Horowitz did.
Conservatives are better off because of it.
My favorite thing about David Horowitz is that while his politics have changed, his stupidity hasn't. Used under License.
