I don't really fault people for being uncomfortable around someone with HIV, and certainly not their choice to avoid sexual contact. Neither does the video you showed. It's just saying don't be a dick about it. Don't call someone gross.

And I would say someone who has AIDS and doesn't tell the person up front is a piece of shit. But these are posts that attack people who were honest about it. There are safe ways to have sex with AIDS, so why shouldn't these people find someone who's willing to put up with the hassle?
