Sooooo.... basically, what you're saying is that everybody should be in a commited, monogomous, heterosexual guarded-by-government-wedding-vows relationship.
If you don't, you deserve AIDS?
Yeah, monogomy works for me and maybe it works for you. BUT IT DOES NOT WORK FOR EVERYBODY. They shouldn't have to live their lives your way so that they get to live at all. When you try to get premicious people into monogomous relationships what you end up with is people doing a lot of cheating, which makes it more likely for their unsspecting partner to get AIDS. However, if people aren't adraid to be open about how a relationship will work, maybe they'll know what they're getting into.
And do NOT tell people with AIDS not to have sex. That's completely ridiculus. Plently of HIV-positive or AIDs-positive people have sexual relationships after they get the news. They need to be honest with their partner(s), and upfront about it, and obviously use protection. However, there are some people who can are willing to be in a sexual relationship with somebody they love, even if they are HIV-positive. Sometimes love is worth the risk.
Don't sit there and say "it's their own fault, who cares?" That can be said true, they did have a part in the fact that they got it (obviously) but the fact is, as I said, we are all reckless people who do reckless things. If you step on a nail in your socks, and get tetnus, I could just as easily say, "Well, if we all wore shoes at all times... So really, it's your fault."
