To the person trying to argue that falling for a coworker when you're married is the same as falling for someone of the same sex,
No, its not the same. First of all, even though you don't want to fall in love with this coworker, you are. Its a matter of what you do with that love. You can act on it or not but none the less you are in love with them even though you may not want to be. You can't change that. The only thing you can have any control over is if you act on it or not. You can do the right thing and try to supress your feelings even though it won't make them go away or you can lose your current spouse and go for it. The difference between this situation and being gay is that if you go for your coworker you break your promise to your spouse and hurt them which is horrible but if you're gay and act on those feelings with someone you have fallen for then not only do you not hurt someone, you have found love that can you can act upon. You get to live happily ever after without hurting anyone. If this has really happened to you then I think you'd be be understanding of people who are attracted to the same sex.
Moving on to the horror stories about the scariness of gay life......
Just about anything that is said about multiple partners or harassing people can be said about straight people. One person was going on about how the vocal idiot gays of their community would call out and try to get men going by to perform sex acts with them. Are you an attractive woman? Have you ever walked past a construction site? If the answer to those questions is yes then I'm guessing that the construction workers probally did the same thing at least once or twice. By the actions of the more vocal idiotic minority and using the same logic it could be said that all men in general treat women the same way. So in this story it happened to your dad. Big deal, go ask your mom how many times the same thing happened to her.
Going on about the gay bath houses is another thing. True, you don't really see as much of that with straight people but I'm guessing that guys at least wish that something like that could be available. Hey, a place where you could easily get laid at without any strings attached would be quite popular with many men (especially the idiot construction workers mentioned in the last paragraph). For all that how do you think prostitutes make their money? Somehow its not so bad when straight guys do stuff like that but it suddenly becomes something horrible and evil when gays do the exact same thing.
Also, the thought that gay people are all big pedophiles out to seduce children is rediculous. I've got numerous friends including one who is in a very happily monogomous gay relationship. Out of almost all my friends I probally feel more comfortable having him watch my son than I do with any of my other friends. He and his partner are kind, caring, funny, and are both just great with kids. That's a lot more than I can say about various other people that I know that are both men and women.
Back down the bullies to the back of the bus
Its time for them to be scared of us
