First, just because I oppose discrimination doesn't automatically make me a "leftist". Second, I was being sarcastic not because discrimination against whites is a problem, but because you think it is. I didn't think I'd have to point that out, but now you know. And third, I wasn't complaining about whites in positions of power, just pointing out that they're there, to rebut your point about discrimination against whites.
Why should I have to do someone else's job for them? The police are hired to do a job and are paid to do it by taxpayers like you and me. If they're not doing their job, wouldn't you as a taxpayer want to know?
