Here again, differentiate between criticizing the Pope, and holding the Catholic Church accountable for his absurd statements. Bigots see what they want in his ambiguous proclamations (the confusion serves his purposes) and use those statements to bolster their hatred for the Church.
Do you deny the bishop of Rome has the authority to change what the church of Rome is allowed to do ?
Yes, and any Catholic worth his salt will tell you that a Pope cannot change fundamental Church teaching. Yes, Francis would like to declare a gay union a marriage. He has shown he would also remove all stigma from divorce too. The best he can do is create confusion and encourage defacto changes. He's a horrible leader and will have to answer for what he's done.
