By law none of that money can go to payment for abortion, but you might check me on that.  But it's still a valid point - why should an action (giving without religious conditions), not be tax exempt being as it serves the general public?

I do believe the laws preventing taxation on church activities should be tightened, and Rep Charles Grassley took a swing at millionaire evangelist a few years ago, but was shot down by his own party.  For that matter executive pay at non-profits should be questioned for organization seeking non profit.  (profit can lead to exorbitant salaries, that eat away at the size of claimed income, and prevent 'paper profits' from being rewards).

I have no problem subsidizing churches providing shelter when public shelter is not enough to cover the need.
