Depends on what you mean. If you mean to exclude those pursuing homosexual relationships, I can certainly agree they have no place leading the church but I am not one to support married clergy of any stripe.
Should those living chaste and celibate lives be excluded? I don't think it's necessary or prudent.
I've never known a caste or celibate gay man. I believe it is a negative psychological compulsion resulting from an early childhood sexual trauma that if not resolved will always find a way to be expressed.
