"I never claimed that a State can establish a state religion, and I would be vehemently opposed to any effort to do so."
You are right, you didn't say that explicitly. What you did say was that the prohibitions of the 1st Amendment apply only to Congress, and not to the states. So what else is there in the U.S. Constitution that would prohibit a state from establishing a state religion?
I think I will try this "tyranny of the lone protester" thing and challenge the govt. school's right to give my 12 year old daughter an abortion without my permission! (legal in California!). Do you think I have a snowball's chance in Hades? It's all about ideology, not objective right and wrong and you know it.
