Plus I believe you can have open discussions and say "I disagree with that entirely" without adding "and you're a bigot" at the end.

Man, you'd think so. Wouldn't ya? But I haven't heard that type of discourse in a long time. I know people who accuse anyone who doesn't agree with literally every point they make of being bigots. Just today I was talking with a friend who accused a person with a blended family of being a racist. I see the same thing every single day online. Go find some 10 year old Reddit posts about politics and read the comments, the tone and the communication is completely different than it is now. It's getting pretty bad out there.
