The trouble is, that is becoming increasingly difficult to do. These days, if you are connected in any way, shape, or form to any tax base of any kind, you are becoming subject to government abuse. Even if you are not connected to the tax base, you are still subject to interference from from aggressive groups like the ACLU, who, by the way, will use government money against you. Simply saying "don't feed at the government trough", I'm sorry, but that's no answer.
It is the answer in the situation I cited.
Almost 30 years ago when I put my kids in a Baptist Church school I was told that if I ever accepted any form of gov. aid because my children were in church school they would be removed from that school.
