Natural Law, that excerpt "hit" over a thousand times in a Google search. Don't presume that because it exists on a banned site it was therefore copied from that site.
The banning of a site does not make everything the site quotes also banned material. For instance, the banned sites quote the Bible but the Bible isn't banned on the Religion Forum simply because they quoted it.
With the rampant plagiarism in recent anti-catholics posts and the thematic parallel between the content of them and the banned sites I am not prepared to give her or anyone else the benefit of the doubt that they do not themselves display with respect to the Catholic Church.
If it is perfectly OK for some to assume and post the worst about the Church it is equally OK for Church members to assume and post the worst about those that offer up that garbage. When they are repeatedly caught red handed it is even more fitting.
