I don't see how correcting a problem is violence. It's more like giving a kid a cookie when they didn't get one. Sure, the other kids will want to keep getting all the cookies, but that's not right, no matter how much they complain.
Except it’s not the same kids. The kids who used to get all the cookies have already grown up. You’re punishing different individuals, just because they have the same skin color as someone who had unfair advantages in the past.
