They already HAVE gay dating services. No, what this lawsuit is all about is their need to take away our choice to be attracted to the opposite sex. That bothers them so much they can't stand seeing other people happy. If heterosexuals can date each other of their own accord, gays have to take that away from them. For the Left, tolerance has come to mean not accepting other people's lifestyles, but denying other people the right to pursue a lifestyle it views as politically incorrect. At their core, these people are hostile to a society of free individuals. They want to assimilate every one into a uniform collective - controlled by THEM. And they never want you to forget they run your life.
"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelologus
