It's my contention that no religion has the right to tell me whether a gay person can be married, or whether a rape victim should be allowed to have an abortion. It's not their right to decide.
Amen to that ;-)
More than that, it is not their right to tell any gay person themselves about marriage, and so on.
I am not sure why a country with so much emphasis on personal freedom (and so it should be) tolerates the influence of the church.
