This particular event had/has nothing to do with Gay rights or pride. It's about desecrating a city that is held as holy by the three largest religions in the world. It's about revenge for having dared say that homosexuality is immoral. The ultimate goal of the radical gay rights movement is to gain control over what religions can and cannot say, do or think. Their own rights are a minor consideration, they want traditional religions to suffer as they have.
Or basically, it's a " In your Face .. defiance " in the face of God, God's Holy land, and God's people.. the Jews & Christians.
