'Different types of sex carry different risks of AIDS. This has nothing to do with sexuality, although if you look at it entirely illogically, you might conclude such.'

how is it illogical?

if groups A is statistically more promiscous and engage in 'higher risk' sex than group B,

then

what is wrong with recognizing that (at least at one point in time) , these groups are also divided along homo/hetero lines?
