Question about lost tax money from religion

In what sense is this "lost money"? Are you proposing to start taxing other charitable and non-profit organisations?

I don't think tarring the whole enterprise with the teleevangelism brush is particularly fair or sensible. Think more of your typical church. It provides a number of services, paid for by donations - I don't see that as an abuse of non-profit activities. What the church does or doesn't give to charity is largely irrelevant; the core activity is non-profit.I assume teleevangelists themselves still pay tax on income?

Well, they should pay their taxes. That's a seperate issue from whether the church itself is being taxed. Again, I'm not talking about "charity" outside of the church. The Church's business of being a church, providing worship, and spiritual support is rightly considered a non-profit and thus tax exempt activity.

Because it's not a profit making activity.

Being non-profit does not preclude an organisation from maintaining a reserve.
