Can you name one single church that has ever run afoul of the IRS for preaching the Gospel?
This legislation is a fix for a problem that simply does not exist. Any misconceptions about what registered churches are allowed/not allowed to do can be cleared up pretty simply through education -- not passing yet more unnecessary laws -- something conservatives should unite in opposing.
Unless, of course, some people who are for this legislation merely want to grant an advantage to churches that every other 501 (c)(3) non-profit would not enjoy.
