On Sunday a group of protestors went to the LDS Temple in Oakland California and were demanding that the church be taxed on its property and investments. There are federal tax authorities and state tax authorities. I doubt this group of attorneys/professors could guarantee immunity from local taxation, or federal taxation. The Boy Scouts won the right to ban homosexuals as scout leaders yet it has not stopped the gay rights groups from throwing up every roadblock possible to Boy Scout operations. The issue isn’t whether a specific exemption or law will apply, the issue is whether gay marriage will be enshrined as a basic right because then the laws will tumble at some point down the road. The gay rights groups intend to punish in any way possible anyone who disagrees with their lifestyle choices.
Wow, I didn't know that one. That is Scary.
So, any stare decisis level issue threatens a church IRS exemption if someone wishes to make an issue of it.
How many letters are in the word abortion?
That whole tax exempt thing is just a muzzle - this is not a time to be fearful of losing tax exemption when we could lose a whole lot more than that......
