@brianjakub,
The only thing that matters is the First Amendment and the separation of church and state. The only groups pushing for "alternate" ideas are religious groups and their "alternate" ideas are all deceptively packaged religion. If you think any of what these groups are pushing is about expanding scientific discussion, then you are deluding yourself.
The Constitution isn't limiting education or freedom of discussion, it's protecting "We The People" from religious incursion into government and visa versa. And that principle, simply put, is the single most valuable doctrine any government has ever offered to its people and possibly to humanity itself. It's a principle and a right that must be protected at all cost.
