There are people with that orientation on the forum but there is a difference between individuals expressing their opinion on a free speech forum and an official statement by the Owner. The diversity statement is the official position of Onionfarms. And yes we don't care about your race, ethnicity and so forth. It would make no difference to me if you had a black supremacist or a brown supremacist that signed up.
Yes people bust my balls over my religion (Islam), but guess what, Jesus Christ was trolled, Muhammed was trolled, Moses was trolled. I shrug it off because that's simply human nature. When you run a lolcow forum, it simply goes with the territory.
You also seem to forget that you have registered and that you have committed yourself to be a regular part of this community just like anyone else.
