Dad, Gay people are naturally gay, just like you are naturally left-handed and Mom naturally enjoys shellfish. Sure, there are lots of people who think homosexuality, left-handedness and eating shellfish are clearly wrong, according to the Bible. Many religious people would punish us all to try to get us to change our ways.
I support your right to live and be yourself, no matter what those fundamentalist religious people say! Some day, I hope that you support my right to live and be myself, too.
