Peace,
I don't say gay is choice...... at least not in all people who claim to be gay. Talk to the real hardcore gay people and they'll tell you they've been that way as long as they can remember. That's what your boy Jason Collins was saying. I think being homosexual is a choice for people who are confused. My research indicates that real gay people are that way for an number of reasons namely Genetics and Behavioral Neuroscience.
Peace
