I'll just quote Red Herring on this one.
I'll add that I never said discussion of FACTS is "wrong," just that theories which have, broadly speaking, been the subject of study for centuries and have been shown over and over to be complete bullshit (and arguably, because of our focus on it, damaging to certain groups of people) are free to be labeled as what they are; racist bullshit. Why don't you read a book? Here's something to start with. It's not subversive to repeat bullshit and then cry about "PC this, PC that" when it's called what it is.
