"And Alan - by definition, a hypothesis which discriminates solely on the base of race/culture and which deliberately excludes all other factors is a racist hypothesis."

So, if we think that culture might be the explanation for the massive over representation, we must unthink it, because it is "racist."
No theorising is permissable, or you are a racist.
Stop the debate, or be guilty of racism.
You must not even imagine such a thing.

Quite liberal Lox.
