..is it wrong that I thought instantly "Guy on right, gay, tidier beard, pants fit better"?

I don't know if it's wrong, but I agree, Whelk.

And yes, someday it will happen, dammit!

It will be. It is inevitable. It just shouldn't be taking this long. Some people are just really stalling it, and I think we know who they are.

I have another possible instance of gay/straight twins.
My roommate is dating someone who thinks kissing is gross. He sends off the gaydar in everyone but could just be an extreme geek, as that sometimes sets it off. Maybe a furry. He claims to never have had sexual feelings for either sex. He is 22. His brother has a girlfriend but they don't have sex because they believe in waiting until marriage. Close family, very religious Methodist, so I assume antigay. Everyone of her friends and family is sure that he is gay. He is extremely intimidated by sex. All my friends I have asked have said closeted gay. Is there a chance he could even be merely asexual? Or figure this out any time soon?

It just shouldn't be taking this long. - How could we could possibly speed society up? If you weren't at least in high school in 1972, you missed the fastest turnaround on attitudes toward gays ever in this country, when Bowie toured Ziggy Stardust.* After a couple years of Alice Cooper ramming images down the conservatives' throats virtually on a weekly basis, Elton John came out. That's when societal acceptance of gays peaked and thereafter plateaued. Bowie and Jagger had made it cool to be bisexual, and that had an impact on a half generation of teens, but like all pop trends, it faded. In fact, disco most likely killed any further rise; outside NYC disco was a celebration of heterosexual cool, and the gay component stayed underground. Only the internet started nudging gay acceptance back up, and each step has been given grudgingly.

That's the thing, though. The internet is not nearly as influential as people believe. Influence by shaming is temporary at best, and far more often than not, just a trigger for ridicule and mockery with the opposite intended effect. For any major jump, gay must become cool again among straight male teens (that's right, tomorrow's patriarchs), and not that fake middle-class cool appropriation either, certainly not geek cool, but street-level lower-class cool. As is, societal acceptance moves at the speed of generational flow, a glacial pace. Where are today's rock stars willing to wear mascara, fishnets and lipstick?

* You want to talk to a homophobe? Talk to a 60s non-SF hippy; communes apparently had no tolerance for gay males, and it continues among that group today.

Oh, I have no idea how long it will take and I don't expect things are going to happen suddenly or soon, I was just expressing that I personally think it is a travesty. And I do have faith that it will happen in my lifetime. I think there will probably always be people with problems and homophobia, just like there will be racists and racism, but laws can be changed. Civil rights progress changed laws but there is still segregation and institutional discrimination and so many issues and situations, but the laws have changed.
I am hopeful for every bit of progress and gay rights are the civil rights issue of our time. I don't think the issue of gay marriage is going to go away and I think there will be progress. Right now I think the big focus of gay rights is the same sex marriage issue and I really have hope in progress on that front.

I just wrote this huge big thing that got spontaneously deleted, but I was saying that I am a pessimist, especially as of late, and but I really don't think it is a stretch of the imagination to think there will be positive change. I really don't want to type out everything all over, about civil rights and political savvy, the shame that the death of a prime gay rights activist who is greatly responsible for changing homosexuality from a mental illness and lead forward the movement got so little media play, but it shows what the effort of one man can do.
I really believe it will happen and we will get to celebrate it at every step. It will be a big fight but people can surprise you and you never know what situations will occur that motivate change.

Last night I got to see two of my dear friends marry each other (and I'm still all blissed out from the love floating around that room). All night, I kept thinking "It's so sad and so very wrong to prevent people from doing this. This is A BASIC RIGHT."

It's pretty normal in a lot of countries in West-Europe. I think that bodes well for the US as well then.

I don't think I've ever encountered gay/straight twins. All I have ever met both are one way or the other.
