The difference being that Churchs are private not public institutions, unlike schools, no I wont keep my "superstitions" out of your class, considering that my "superstition" is also a legitimate scientific theory also.

You have it backwards. You cannot prove there is a scientific part to it. The Burden of Proof is upon you to give evidence for your assertion, not upon others to disprove it since that would be a Proving the Negative fallacy.
my "superstition" is also a legitimate scientific theory also.
Precisely the point, ID is NOT a legitimate scientific theory since it has absolutely no evidence to support it.
Oh, another one of those...
