That seems to be something that *is* very racist. (Even if there are cultural differences, you can avoid being essentialist about that.)

I think maybe the problem is, everyone should generally be a lot less racist than they are now, but when I read articles about that, I feel like they're telling me to take it to the logical conclusion, and obliterate any not-completely-egalitarian sexual orientation. But actually they're just being emphatic, not necessarily precise.
