Sure, but “you were mean to me so now I’m joining maga” is pretty silly.
Some people are like that, I guess, but if someone rudely explains how racism is deeply entrenched in the US that doesn’t mean they’re wrong. Rejecting their message because they were mean is childish.






But no there’s no corresponding “leftists are doing something like punching her in the face” in real life. Certainly not “every single” one. I agree that people are emotionally driven ( https://theoatmeal.com/comics/believe is a good comic about it ).
There are extremists in any sect - the christian fanatics, animal rights ecoterrorists, whatever. But it’s not “the left” as a whole, or even a majority.
Unless, I guess, you consider a scenario like
“I just think gay people shouldn’t be so visible. It’s confusing to my children”
“That’s a messed up thing to say. Gay people are a part of life. Shunting them into the closet so you can avoid a mildly uncomfortable conversation is unjust”
to be punching someone in the face.
