I also said "Christian". Are you not equally bothered that I seemed to imply conservatives hate all other religions?
Look, I'm not going to argue the racism angle because it's simply a nonstarter. That conservatism has a history of racism is undeniable. But race is simply not a significant factor in modern conservative politics.
At best, racism has been all but eradicated from the conservative ethos. At worst, it's simply been reduced to a nebulous, below-the-surface vestige of a bygone era. Either way, it's impossible to discuss in concrete terms, and therefore pointless to argue.
But bigotry is alive and well in modern conservatism, and that's why I think it's much more fruitful to frame the discussion with that term.
It's also why I think a lot of conservatives want to make it it strictly about racism. Racism in modern conservative politics is difficult to prove. Bigotry is not.
If we make the discussion just about racism, it allows conservatives to feign offense and proclaim themselves the victims of persecution. If we make the discussion about bigotry, the best response conservatives can muster is "Well, we're not all bigots. Just most of us".
