I reject Evolution, but that does not mean I accept a young earth creationist point of view either. But as CL said, does it matter in the grand scheme of things? I think your main issue is that their beliefs are being passed off as propaganda and attempting to proselytize others. It's an opposing viewpoint which those with an open intellectual mind should listen to and make their own decision to reject or not. I have no problem with it, listened to it and use my own intellect to make a decision on it. It's called an informed decision.
We are not made happy by what we acquire but by what we appreciate.
