Should he have been fired?

I don't even see it as a message of ignorance/prejudice, at least not some of the remarks people are getting upset over. For centuries, blacks were slaves. This is undeniable, and I don't think anyone in their right mind would TRY to deny this. Slaves are severely punished/killed for having/showing any semblance of intellect; it wasn't just the ability to read that they were punished for, it was just about anything. Of course. The slave owners would have been afraid of one slave spreading dissent to the others. For centuries, they were quite literally bred to be workhorses; strong, huge, and powerful, with little thought outside of doing what they were told, because they knew the consequences if they tried. Slaves are literally culled from birth, intellectually. You think that, after centuries, that would have no effect at all on the current generations of black people? It's obvious they still retain their superior physical stature, you need only look as far as athletics to see that much. So, him citing sources that say they have a lower IQ on average is not racist at all, it would be racist to claim otherwise; they are not to blame for it at all, and anything else would be blatant patronization. People say genetics play a huge role in your life, but only when it suits their needs; with things like intellect and mannerisms, most refuse to admit that those are also controlled by genetics.
