Well, you could say that about modern times; things are getting dumbed down so as to be more inclusive.  But, I don't think that was necessarily the case back when I was younger.

Nevermind the fact that dumbing things down is racist in its own way.  If they could just come out and say "Black people are too stupid to learn these things, so we're making things easier for them," they would at least be honest.  And, if they're on the Right Side of History, it'll be swept under the rug.
