You've accused me of being a purveyor of PC - which, in my own sense, I suppose I am. Fine, I offer myself up for examination.
Anti-black racism is bad, anti-white racism is not worthy of attention.
Anti-black racism is a historically-massive social ill. Results of the belief that black people were inferior led to institutional racism, then institutional discrimination and socially-approved behavior like lynchings that flew in the face of the law. Today, the socio-economic effects of our racist past (and that lingering racism that still exists today) have kept African Americans on average poorer than all other ethnic groups in this country with the exception of Hispanic immigrants.
Anti-white racism does what? You've shown several things: TV commercials in which white men are presented as old, out-of-touch businessmen (which you found offensive despite the fact that the majority of people in such positions today are still older white males); ridiculous lawsuits that targeted white men who said something that meant nothing and were accused of hate speech (that one won't last a day in court). Affirmative action in college admissions hurts the middle class suburban white public school student the most - I know, I was one only a couple of years ago, and while it's true that I didn't get into my top choice (or receive any actual financial aid from the government), I still got into college, am able to pay for it, and would have been able to lead a decent (although not affluent) life without going to college at all, working at a store or a restaurant in the area, rising up through the ranks, and earning enough to live out on my own. Affirmative action could have blocked my chances at going to college, but not at living - I recognize that for many African Americans there's no distinction between those two, and so I am not bitter.
Arab defamation brings out the Pee See Marines, anti-semitism produces a yawn.
I've spent lengthy hours defending Islam on this forum, it's true. My point is simple: all religions have it in them to be either hateful and violent or peaceful and tolerant. Christianity, the yardstick by which Westerners measure all religions, also went through it's violent phases - where Christian leaders who made violent interpretations of Christian holy books probably made it look like the religion itself was violent. Just give them a chance.
As for "yawning" at anti-semitism, well - here's a link.

You joined right around the time we were dealing with the invasion of the anti-semites. That thread I just linked you to used to show up on our homepage (back when we had one of those), so everyone coming to houseofpolitics.com to sign in or just to visit would see that nice, big "ANTI-SEMITISM IS NOT TOLERATED HERE. PERIOD."
I guess that could be confused with a yawn, but...
