So, for capital crimes, relying on people's judgement is ok, but not for money matters? I think your priorities may be a bit screwed up.
I think you somehow managed to miss the point of my post. Yes, judgment enters into criminal courts in that the prosecutor has to decide whether to charge a suspect, the judge has to make some decisions, and the jury has to decide guilt or innocence. HOWEVER , those decisions aren't made arbitrarily based on a random person's arbitrary "common sense" judgment. We don't go, "Oh, I think I know who's guilty and who's not, so we'll just put the guilty people in jail."
There are laws and court precedents. When judgement is involved, it usually involves some process where a person is supposed to be applying some criteria that were set by law or precedents. If you don't do that-- if you leave the decision up to some person's "common sense" judgment, you're creating a situation where abuse is inevitable.
So what I'm saying is, if the government is going to have a "tax exempt status" for religious organizations, it should be a decision that is made according to set laws and precedents. I would guess there already is some kind of law here, but I'm not a lawyer.
To racap, you're right to compare the decision to our decisions on whether someone should be convicted of murder. We don't put people away for murder because the general public has a good opinion of that person and would like to see him locked up. We need evidence that they actually committed murder, in accordance with existing law. We shouldn't decide tax-exempt status for an organization based on whether the general public has a good opinion of it.
