If uality is so easily changed, why hasn't most if not ALL of the gay community chosen to be straight?

Im very sorry about your brother. Like you said, it would make absolutely no sense to choose a ual orientation which would result in hatred by the numerous religious people. My country has less than 2 weeks ago redefined marriage laws to include couples, and also gives them the right to adopt. That gave me hope, one day humanity will break free from the grip of religion.
