I've wondered if I should fuck myself over as protest against what I'm taking advantage of: you know, like if the police question me about something, be honest instead of avoid trouble.
I'm sorry, but protests should never have been and never should be about making this not true for anyone.
The issue isn't that white people are "privileged" in most cases, it's that white people are treated as neutral in the US. There are few stereotypes applied to you. You aren't treated as a criminal, and a police officer will judge you on your words. Truthful and honest works make you have a higher chance of success.
If we break down those stereotypes, it does NOT result in a loss for white people. Never has, never will. Equality is a win for everyone. Unless perhaps in the rare case where it is your word against a black persons, but if you are the sort of person who wouldn't be horrified by the idea and lie to get out of a place like that, you deserve nothing more than a (metaphorical, although literal works too) knife in the back.
Anyone protesting for us to jail more white people for smoking weed, to arrest more white people because black people are arrested too often, are fucking idiots.
Secondly, a lot of ways our system works, welfare, etc, being changed to benefit minorities more will benefit white people also. Even if not as much, it will.
Imagine we shift school funding to be federal and even-per-student instead of based on property taxes. Unless you are the sort of person who grew up in the rich districts of Chicago, had a school with a fancy pool, etc, your school probably isn't going to be worse off. If you are in one of those schools, it's probably likely that the money didn't really help you very much anyways (the first ten dollars matters a lot, the last ten gets spent on aquatic centers that don't really change lives)
There is nothing to lose, and everything to gain.
