Why is race or ethnicity such a taboo subject, ultimately exemplified here on Fluther?

We can talk about language and everything is okay. We can talk about ethnic culture and things are a little on eggshells, but still good.

If race or ethnicity is mentioned, it starts a firestorm. When I mentioned that I liked the Anglo Saxon culture but not exclusively, I was immediately called a Nazi. Now that this firestorm has cooled down a bit—why is it so?

Is it wrong to identify with or relate to one’s own native ethnoi? In my opinion, you cannot fully appreciate other cultures until you understand your own, and vise versa. And ethnic diversity is a very socially and intellectually stimulating thing to explore and appreciate.
