Why bother to try to teach. Someone is going to be religiously offended by nearly everything. By the time you water it down to an acceptable pablum, you won’t be teaching anything.
And that is what some people want…the Bible should be the science book, the history book, the literature book and the psychology book.
That is not going to work if you are also accommodating the Jews, Muslims, Catholics, Calvinists, Pastafarians….
The Christian Privilege is not truly concerned about the “others.” As you know, if it was a non-Christian faith taking a stand, the same groups would not support similar bills, I would speculate. They disguise a lot of these discussions under organizations and bills with terminology such as “Religious Freedom” when in it actually means “Christian Rule.” If they truly were advocating for religious freedom, they would discuss all world religions, to include openness toward atheistic ideas. If they wanted religious freedom, they wouldn’t have spent the first four years of the President’s first term trying to figure out his “true” religion, it wouldn’t have mattered.
