It's okay with me. I mean, I don't recommend it, but you're certainly allowed to.
Gay people are challenged for our action all the time. Hence the overreaction. Telling them they're not allowed to criticize Christians isn't going to make their anger go away. If you'd like to change things, join the fight for equality for gay people. Stand up and challenge the homophobia of your church and your Bible college. When gay people are no longer marginalized and persecuted, they won't have so much to be angry about. As it is, gay people have plenty to be angry about. Christians have deprived us of equality and justice; do you really think it's appropriate to try to deprive us of our anger, too?
