@rosborne979,
Your last post implies at least two factual claims that are false, or at least dubious:
Claim 1: vouchers redeemed at private schools come at the expense of a public school.
This claim is dubious: Although public schools miss out on the benefit of the vouchers, they also save the cost of schooling the students whose parents opt out. To a first approximation, the profit margins of public schools, if any, remains unchanged under the bottom line.
Claim 2: School vouchers violate the non-establishment clause if redeemed in religious schools.
This claim is false. Admittedly, you could have made a reasonable case for it until six years ago. But in 2002, the Supreme Court considered your claim in
Zelman v. Simmons-Harris, and rejected it. If you make a legal argument, you have to make sure that your legal facts are correct -- and in this case, they aren't.
