There's plenty of acceptance of homosexuality and abortion outside the Church, too. People not following the faith is not an argument against the bible, and it isn't an argument against the Church either.

A random Church in San Fran being evil is not an indictment on the entire institution, which still hold (and in the current political climate no less) that abortion is a sin, sex before marriage in a sin, contraception is a sin, and homosexuality is a sin.

Not one doctrine has been changed in the last 100 years. Expanded, sure, but not changed. In our current world, that is unthinkable. In on current world, they should have folded on contraception, sex before marriage, and 1st term abortion long ago. God won't let them because the Church belongs to Him.
