Whoooah, looks like you're projecting homophobia onto this, and respectfully, there's no place for that here. This is not at all about homophobia. This is about the fact that most men see women as harmless, yet would readily recognize another man as a potential threat because of men's (generally) greater strength and stature. I illustrated this point with this particular comparison because many cishet men think that being touched by a member of the opposite sex is flattering, but they completely overlook the latent threat of the physical size dynamic that this imposes upon a woman. Inviting them to imagine being touched by someone of at least similar (and sometimes greater) size and strength as themselves helps make the discomfort of latent threat clearer for them.

Lack of consent is lack of consent, and it is equally egregious regardless of the genders or orientations involved — so one need not be homophobic or disgusted in order to recognize that an uninvited touch is problematic. I can't help if some readers are bigots who would react with disgust at my example; homophobes have broken minds are a whole other set of problems. :(
