I understand what you're saying, and I disagree with many of your points. I think that they are born out of an ignorance of gay people. Understand I'm not saying you're ignorant, I just think that you are not well versed on the subject. BTW this is a great thread, and question. I was born and raised in SF, so I've lived knowing gays, and gay couples who have raised kids, my whole life. I had friends of mine when I was growing up who had gay parents, so this is nothing new to me.
Honestly, the households with gay parents were no different from the ones with straight parents that I grew up around. Sometimes they were better, sometimes worse, but one thing that must be cleared up is that these "gay" households were not like some S&M parlor, with The Village people playing on a 24hr loop. I mean, I knew more "straight" households that were dysfunctional than the "gay" households I knew of.
I guess the real point that I'm trying to make is that these so called "gay" households were no different in terms of child rearing, there was love, understanding, and support... Sex, and sexuality was no more of an issue than in any other house.
In terms of a "real" man, and our definitions of real, yes you are right, everyone's deffinition will be different. That being said, my friends who were raised by gay parents, 2 of them, both men, have grown up to have integrity, be responsible, successful, and just all around cool people...oh and BTW they're both straight. In all my years, I've never known of a gay person pushing their sexuality onto anyone, including their kids. The preconcieved notions of gay people being so different from straight people, (obviously, I'm not speaking on the obvious difference), needs to realised and overcome.
