> HIV isn't transmitted through spitting.

I believe you are correct. I have no clue whether vaksel is American, but I do think Americans (I'm one) have absorbed--been fed?--a fair amount of hooey about HIV transmission and how to be "safe." Keep in mind, if you're old enough, AIDS was/is "that gay disease" and something quite a small number of injecting druggies were getting--as the "need" for a War on Drugs was building. I'm sorry to report, Americans are a fearful lot.

If you absolutely KNEW that someone had HIV and they spit (say) into your mouth, wouldn't you worry about it at least a little bit? Even though you know it's silly?

I think most humans are irrationally fearful about things like HIV.
