Challenge away. First, there are no mainstream Christian churches in the US that allow these types of abuses. Secondly, if you are referring to some “odd ball” church that claims to be Christian, they are subject to the law on abuse.
What goes on in many of the countries in the Islamic world is religious-sanctioned and state-sanctioned abuse, torture and murder. Its not some “odd ball” sect of Islam…Wahabism is practiced in large numbers in countries like Saudi Arabia. This is one of the most extreme sects of Islam that appears to be fostering the Islamofacists that think its ok to blow up babies to achieve their goals.
There is absolutely no moral equivalency between what happens there and what happens here.
