Yes, the gay community just loves the Catholic Church. /s.
Actually, a lot of them DO:
National Association of Catholic Diocesan Lesbian and Gay Ministries.
I'm not saying the RCC officially sanctions any of these groups, but there are TONS of them. This list doesn't even scratch the surface. Out of curiosity, I did an identical search for Southern Baptist gay organizations and came up with zip, zero, nada of them. I thought that was pretty interesting.
I see your three links and raise you a million..

It is true that the Catholic Church will never, ever, close her doors to any sinner, and it will never, ever, change her teaching about sin. What's not to love?
