Chastity is 100% effective at preventing STDs exactly like living in a plastic bubble is 100% effective at preventing the flu (incidentally, it's also 100% effective at preventing humanity from existing within 80 years...). The fact that people throughout history, even in the most repressive times when "adulterers" were stoned or forced to marry rapists, have had much higher rates of STDs than we do today, shows that reality, rather than an abstract ideal case, is what matters in terms of public health.

Put another way: a "slut" practicing safe sex today will have fewer chances to contract an STD than a regular married woman in Victorian times.

Seriously? Your argument is "damn those slut whores" and you're pretending to have an intellectual high ground...? Have a good weekend.
