Don't make it a crux issue for Christians, because while many Christians will say that it is a sin, they don't give a fuck what you do, and that shouldn't be the point or even brought into the matrix of what the problem with what Phil said. People sin every day and it's up to God to forgive them. Masturbation is a sin. Saying curse words is a sin. Sex before marriage is a sin. People commit 'sins' and they don't equate to things that hurt others like murder or exploitation or lying. There are different levels of sin, and it's all, according to the fundamentals of the faith, between you and God. The social fundamentalist moralizing and discrimination against minorities has nothing to do with sin, and everything to do with how people use religion to control and suppress people they don't like or feel threatened by.
So if you try to make this an issue where Christians have to say whether or not homosexuality is a sin, that is a valley that doesn't need to be crossed really. Phyric victory with lots of fallout, when instead it's already established as a civil issue of public disrespect to an innocent part of the community that can be pressed along those lines. Some people would want to turn this into a religious crusade, like Phil and the gang with his 'righteous path' rhetoric have already started. But it's senseless and unnecessary. I say let them enter the valley and starve.
