You make the assumption I wish Creationism to be taught as science. I do not. You do not try to teach about apples in a class about oranges!
If you check my posts, I specifically said NOT necessarily in the same class.
There is nothing wrong with creationism in a theology/philosophy class. This is not to push religion. Like it our not, our country is founded on Judeo-Christian beliefs. We are endowed by our Creator with unalienable rights. Rights untouchable by government because they were not granted by government.
This class could cover Socrates, Locke, Batiste and Montesquieu along with creationism and the Bible's role in American law. I have a set of school textbooks from the 1800's. Biblical lessons were often integrated into these books. They were just decent, moral lessons on not stealing, being honest, etc.
Guess that was before a classical education got run over by the 'progressive' one.
On the other hand you have to understand that what you propose is not what this conflict is about. As far as most scientists are concerned you can teach in a theology/philosophy class whatever you want as long as you don't claim it is science.
But this is not what many creationsts are satisfied with. They want to pass off their theological opposition to evolution, geology, astronomy, radiology, etc. as equally valid as mainstream science.
