It's really hard to get anywhere if it requires explaining everything from first principle. I'm also really sorry for overestimating people by assuming that "do not grab women by their genitals without their consent" or "do not shoot people for fun – even when they're African-American" don't need further justification.

And yes, I am, just now, calling these people idiots. Because their argument seems to be "I don't like how you're making fun of me, so I'm gonna find some bystanders and beat them up, because I know how much it hurts you to watch people suffer".

I'd also say this "condescension" has always been a two-way street. All the talk of "real America" has, since at least the Sarah Palin disaster, been a way to insult "the elites".

The talk of 'real America' has been going on since the founding of the country.

And if they can't be convinced? At a certain point accommodation becomes pointless. How do you convince a racist not to be racist?

The point is to not convince, but to make the playing ground such that the act of discrimination provides negative value towards the actor.

The only way to change the playing field in that way is to have a majority of people feel the same way, which requires either convincing them or waiting until the old group dies out.
