If we're basing revulsion based on cost of diseases spread, vaginal sex would also have to be considered disgusting. Actually, you'd have to view quite a lot of non-sexual activities with revulsion as well based on that premise. Sorry, but I don't believe it's any more gross or decent than any other consensual sex act.

> Do you think we've totaled into the billions in costs related to diseases spread primarily by sodomy?

We should probably ban preschool/kindergarten on those grounds, then.

Uhh... straight people have anal sex too.

You asserted that unsafe anal sex is a problem. You're okay with safe anal sex then.
