Right, because with the advent of contraception and the sexual liberation of women, heterosexuals aren't as promiscuous? What, in this day and age you don't have bi-sexed social groups?
And the guys not wanting to shower with a gay man are homophobic due to the difference in reaction. You don't see women beating men to bloody pulps for a wrongly perceived look; their socialization into sexual modesty is responsible for the anxiety. Does every woman you come across treat you as a potential sexual predator? Because that's what all the drop-the-soap jokes are about among straight men, the depiction of gay men as predators eagerly awaiting the moment to take and ravage the poor straight men's virgin asses, degrading them into effeminacy.
And what the hell do you mean with the implication that gay men can't interact without a latent sexual tension? Especially between a 36 y/o and a 16 y/o, which constitutes statutory rape. Why would the boy be less resistant, and why would the older man be predatory? The depiction is not only sexist caricature of males, but ignorant assumptions about gay male interaction as well.
I came out of the closet when I was around 15, and at 22 I interact with older gay men just fine; so no, I wouldn't mind a gay son interacting with an older male. I don't adhere to silly Puritanical vestiges in our culture. Dealing with older gay men helped me in terms of guidance. What situations they had gone through that I could avoid, which places were safe for me to go around with my boyfriend, which businesses were friendly and we should endorse. My mother never insisted to me to be safe and caring towards the men I sleep with by using a condom. The counsel of older gay men did. It wasn't my father who warned me about certain practices, to avoid taking strangers home to sleep with.
Role models don't need to be considerably older than you. Think what some 15 year old gay boy might seek a role model in his favorite bands, movies, programs. How the 18 year old hetero boys have people to emulate all over, while we're starved of visibility.
Over-represented in the media? Where do you live?http://www.glaad.org/eye/ontv/2008/where_we_are.pdf
That's not even close to the often cited 8-12%. Can you tell me in which MAINSTREAM (hint, Brokeback Mountain and Milk don't count) movies or TV have we had a fleshed out gay protagonist that doesn't revolve around AIDS and other stereotypical depictions of gay people? A protagonist who is gay but treated just like any other protagonist with the same standards.
P.S. God, this person just lives for antiquated stereotypes. Are your "gay friends" so comfortable with your depiction of them as sexually-compulsive predators?
