How Can They Belong?

Just a question in my own mind. I am hoping someone can answer it for me. How can someone belong to a group/organization that hates, well maybe hate is too strong of a word, but that dislikes you and treats you like second class? I am specifically referring to gays that belong to groups/organizations that speak out against gays. I am not talking about groups/organizations that at least publically agree with gay rights and then speak negatively about gay rights behind closed doors, but openly denegrate gay rights. Two such groups/organizations come to mind, the Catholic Church, or any church that condems gay rights, and the Republican party, at least as we know it today.
I know of gay individuals who, every Sunday morning, have to get to their local church for service. The "good little Catholic boys." Go to church, pray to God, and listen to how terrible you are for being gay. Well, maybe you individually are not terrible, but the lifestyle you choose to live is. I used to belong to such a church. We were told to "love the homosexual, but not the lifestyle." I have since found out that you cannot seperate the two, the person and the lifestyle. A person lives the lifesyle in which God created them to be. I know the Catholic church in particular tends to indoctrinate individuals into the "sense of guilt" feeling, but come on! This is America. A person does not have to belong to any such church. (At least not yet).
Then there's the gay individuals that love the Republican party. There's the Log Cabin Republicans, gay Republicans. How can someone give their time, money, and support to a party that treats you like a second class citizen? The US Constitution grants the same freedoms and rights for all Americans, including gay Americans, but the Republican party doesn't think so. Help promote the belief that gays are less than American by supporting such discriminatory beliefs and practices. Aid the Republican party, controlled and manipulated by the religious right fanatics. Keep it up boys and girls, and you too will be right where the "masta" wants you to be, in the closet, cleaning his boots, and maybe giving him a little "relief" when he needs it.
It just bothers me when individuals think so little of themselves to be a part of any organization that belittles them, that makes them second. Are gay Americans so self loathing that they will keep on assisting these groups to keep us down? That is the sad thing about some gay Americans, not that they are gay, but that they are ashamed and afraid to stand up for who they are.
