There is nothing about the lifestyle that is dangerous, Ake. There is a transmission vector which has a statistical correlation with certain sexual practices when they ar epursued unprotected. The same statistical correlation can be found relating to unprotected hetero sex as a transmission vector for syphilis, but no-one goes around saying its the "hetero lifestyle". That's just armwaving. Butt-buggery, whether done by heteros or homos, without protection, is a good way to pass on a disease. Any disease. That has nothing to do with the issue of the right to marry being denied some people.
