Let’s suppose they were only teaching Creation/ID in the public schools. Should students receive D’s or F’s for challenging the science behind these subjects too?

There's science behind ID?

If ID was what was being taught and the students challenged it with evolution facts then wouldn't you expect them to be graded down?

Absolutely not. As long as they made a good case for their position, I would give them high marks. Conservatives tend not to go in for political correctness.
