It doesn't matter.
Just because Christians support something doesn't make it an establishment of religion.
For Pete's sake, Christians also support "telling the truth." If they lobby for a law requiring honesty in legal proceedings, does that mean we should excise truth from our legal system because it establishes a religious tenet?
Besides, there even if they allowed churches to put church-paid "What Would Jesus Do?" stickers in every textbook....EVEN that would not be an establishment of religion.
Established religion is a state-sponsored and supported religion in which one is taxed to support the religion, and non-membership in the religion prevents government service.
Certainly not the young earth creationists! The yec's lie. Lie about lying. And, post links to yec websites that quote more lies for the other yec liars to go around lying about.
ROFL!
Good one. But seriously!
So, you are OK with "Go Jihad with muhammed" "What would Satan Do?" "Thor is the source of all power" "The Goddess wants you to preserve the planet" "The Flying Spaghetti Monster is your only hope" etc. etc. etc.
Where does it end? Who chooses? You?
