racism is itself based on religion
You can't compare race to sexual orientation. First of all, race with respect to skin color is inherent, but who people are attracted to is not fixed, not inherent, and it can be changed over time and experiences. You can choose not to believe that, and stay stuck; or take the truth and run with it. If you, or someone you care about values a gay lifestyle or relationship more than God, then that's your choice, but even if you get full control of the government, Christians will always choose the word of God, and never approve of that.
homosexuals don't have or want sex change operations
I'm telling you, if you really care about gay people- this narrative about sexual orientation, and gay-marriage is the wrong path; it doesn't serve them in any way.
