Whenever you see a mod ban something for bigotry it's a safe bet they are the bigot. They are intolerant of views different from their own, which is the definition of bigotry.

What that modpost means is: I support trans people and homosexuals and I find that sub offensive, so I'm going to ban it from being linked.

If that sub were making fun of racists, white supremacists or homophobes, do you think it would have been banned?
