I don't believe that you should be downvoted. If you read Paul Graham's essay
http://www.paulgraham.com/say.html, it is clear that our current hypersensitivity to racism is a current moral fashion. You're not allowed to be racist, you're not allowed to think racist things, you're not even allowed to question our society's chosen approach to racism.
Which is just silly. Facts remain facts even if we don't like them. And we can't honestly discuss certain facts without sounding racist.
Here is a real example. "On average, blacks have lower IQs than whites." How careful do you have to be when saying this? Very, you could get into a lot of trouble. However this statement actually happens to be true, and repeatedly demonstrated in various places in various ways. With some bizarre consequences. For example the Supreme Court has ruled that it is illegal to make an IQ test be part of a job hiring practice because allowing it will discriminate against blacks. Don't believe me?

But we can't even say facts like this in public. And if we can't say it, we can't start asking honest questions why it happens. And without asking them, we can't begin having honest conversations about what we can reasonably do to address the issue. Instead we're stuck at name calling and denial of reality. (And telling people who actually are racist that they can't talk about their racism doesn't actually reduce their racism - it just increases their resentment of the larger society, which ironically they are somewhat likely to take out on the group they are racist against!)
