Well, possibly because that's a textbook definition of bigotry right there, and I don't feel that bigotry is something we generally need more of. Even if it is - as I suspect in your case - something of an act.

Happening across some of your other posts, you seem to be a person who likes to make sweeping generalisations in the hope of offending someone. I suspect that you're well aware of what you're doing and are doing it intentionally. So I'll wish you good luck with that and be on my way.
