General Discussion

They are comfortable with what they are comfortable with.
The old excuse "well, but our friend who's (queer, Trans, Muslim/Jewish/Catholic, undocumented, black, ect...) is different - they are polite, kind, articulate, helpful, honest... You've all heard the excuse why they're against the politics or codifying that person's civil or legal rights - but not that person.

"Why do you all have to be so decisive?"

Totally ignoring that the "Normative", that so called average American, is still a White 40-something professional male who owns his own house, has a wife and one or two kids. And everyone else plays second fiddle to "that guy".

Even so, most US Americans tend to side on "fairness" if they can feel good about being fair, like they're one of the heros.
What they don't like is "in your face" yelling or black and white ideology - or the idea that Mr. Norm might have to check his privilege on a particular right, because they, also, might have to check theirs, and that's bad - because that might mean they don't deserve what they've "worked hard" for and might have to give up what they've earned.

Not saying this is an excuse for any of their political inaction or overreaction, but just my observation. It's the seduction of the private justification of comfort.
