Is it time for religious groups to lose their tax exemption?

Is it time for religious groups to lose their tax exemption?  Religious groups actually play quite a bit of tax through their employees.  Any move to a consumption tax would like have them pay taxes on their entire payroll, plus withholding income tax for highly paid staff members - rather than simply serving as tax collector to collect from their employees.  Either way, donor money is taxed (as it should be).  Also, when religious organizations rent space, they pay tax through their landlords.  When their employees pay property taxes, either directly or through their landlords, it also comes from donors if you look at it honestly.  Again, as it should be.
