That's a valid question, but I would point out that when the Vatican stands up and opposes a host of depraved, nihilistic radical feminist and population-control measures in the United Nations, it usually finds itself on the same side as these Islamic nations. And on the other side of the table is a group of ugly, bitter, Satanic screeching banshees from the United States and western Europe.
When the Islamic fundamentalists toppled the government in Iran in 1979 and deposed the Shah, the U.S. embassy was the second building they sacked in Tehran. The first one was the Iranian headquarters of Planned Parenthood.
Just an interesting little tidbit to put things in an interesting perspective.
