Please point to the Catechism allowing for gay marriage or abortion, or Hindu practices. You should know better than to confuse doctrine with individual opinions of Catholics. Protestant denominations exist that allow for abortion, gay marriage, or gay lifestyle doctrinally.
Rome has guidelines about homosexuality. For chaste men with homosexual inclination monastic life is OK. Priesthood is not OK.
Having a piece of paper saying what the "official" policy means nothing if you have a bunch of bishops and sisters running around advocating their opposing views. Rome may set policy from the safety of Italy but they do little to hurd in their wayward flock. Does practice what they preach come to mind?
There are very few Protestant groups that allow these sort of things and those that do are finding their denominations dwindling. It would be beneficial to recongize these modernalistic dangers in all of our churches/Churches. This isn't isolate to a select group.
