I've long said that the way to stop prejudice is to stop being prejudiced. A liberal will argue with that, and the arguments are the same as those we hear when we say "All Lives Matter."
Liberals just can't get it through their skulls that when they do things like Affirmative Action Quotas, they are creating a whole new generation of aggrieved haters. The last time I had that discussion with a leftist, she ended up proclaiming "White males need to see what it's like." I said, well, I guess minorities need to see what it's like to be hated more than ever, because that's what you're asking for, and will surely get.
Act childish, and you will be treated as a child.
