I wouldn't hang out with cacs unless you can benefit someway and not in arbitrary forms like companionship.
Otherwise it's too much of a headache dealing with their faux outrage, apathy, ignorance and especially their passive- aggressiveness. This trait seems to be near universal among the ones I've met.
Along with fact that they always slip up, test the waters asking passive aggressive (again a near universal trait) questions and doing things to test your paitence, almost like they're conducting a personal experiment trying to figure out if what they say about black people is true.
Best believe they'll talk about you behind your back too, especially at work.
It all stems from the refusal to perceive us as rational thinking, free, intelligent and capable human beings.
That's OK. We don't need their acceptance or acknowledgement to recognize we are all the those things and then some.
I'm not saying there is no such thing as a chill white person, just that in my observation of reality and society 95% are this way. Personally I operate under the assumption that even if they are chill they are going to flip.
It's up to your personal discretion and ability to judge a persons character however. Nothing I said was wrong though if you look at your own lives you will see the common ground.
