Creationism is founded on the intelligence of people now and in the past that the bible and natural evidence support our ideas.
Then creationists should be presenting this evidence to scientists in the arena of science. They aren't. Until this happens then creationism can not be considered scientific, and that only leaves its religious underpinnings.
to deny creationism is to deny religion as true by your reasoning.
No one is denying creationism. What we are saying is that creationism is not scientific, and is therefore inappropriate for a public school science class. Creationism would fit in nicely in a World Religions course if one were offered.
Where origins are taught should the truth be taught.
We aren't talking about origins class. We are talking about science class.
censorship either means the truth can't be taught of the side censored is wrong.
The government is necessarily censored in what it can say. Teachers in public schools are not allowed to endorse a political candidate as part of their teaching duties, as another example. We, as a nation, have decided that people in the pay of the government should respect the citizen's religious and political freedoms by staying out of the discussion.
If you want to claim that creationism is truth then that's fine. Have at it. It is not the business of the government to decide which religious views are true and which are not. What I will argue against is that creationism is science, which it isn't.
