Who is "we"? Looks to me like about half of the posts in the thread are talking about the connection.Luckily we're not talking about charities, we're talking about churches.
But there is so much shooting from the hip in here, so little connection to reality. Here's the law on churches as non profits: http://en.m.wikipedia.org/wiki/501(c)_organization#section_1
Now, if we revoke the tax exempt status of churches because they don't do enough charity, what does that say for the other organizations on that list?
