They were perfectly happy to let trump F everything up as long as it was everyone else getting F’d. As soon as it inconveniences them, they suddenly find some kind of righteous morality.
Yes. That's partially because many Americans are racist (or at least willing to throw someone else under the bus) and weak-minded, and partially because our education has been intentionally dismantled by the parasite class.
Now, are you more interested in lauding your own moral superiority over them (thereby making them feel unwelcome in spaces and communities able to enact actual positive change) or are you more interested in building working class consciousness?
You have to pick one.
If you're a marginalized / vulnerable person, by all means stay away from these people because yes, they are largely indoctrinated garbage and will probably make you feel unsafe. And you can disregard everything I'm saying in this comment because it's not my position to tell you how to respond to that danger.
But if you're a white liberal (not exactly a longshot guess here on Lemmy), then that is your responsibility. You aren't going to dismantle whiteness by finger-wagging and offering "I told you so" on the internet, you'll dismantle it by showing them another, better way.
It's either that or you round them up and kill them, and I don't think that would be a particularly beneficial approach (except for those convicted Nuremberg style). Otherwise, these people aren't going away and will continue to effect the trajectory of our country. You can try to help heal them, or you can deal with the consequences of them continuing to exist as a moral, spiritual, and emotional black hole.
