There was a recent problem in some state (Texas?) recently where they did attempt to bring in a "religious studies class", but it was pretty thinly disguised evangelical Christian based "religious studies".
The specific case you may be referring to is the one in Odessa, TX, some 60 miles down the interstate from here. For more information:

Yes, the problem is that the class is more about converting the students to the fundamentalist viewpoint instead of presenting a non-sectarian learning experience.
I'm not sure that a truly neutral class in comparative religion prior to college is even possible here. It will either be considered a threat to the personal inerrency assumed by the fundamentalists, or sheer high pressure propaganda to convert by everyone else.
