No, you are talking about an educational textbook for Christian schools, and you are using a page from that book to make false and misleading determinations and insinuations about the whole book. In the process, you are completely disregarding and ignoring the uniform state standards for education that MUST BE MET by every graduating student. Aside from Divine intervention, how else would students learn the things they must know to pass the state testing and get a diploma? Why are Christian School graduates also able to get into pretty much any college they want to go to? Maybe the mostly-liberal universities out there, are all unfairly playing favorites to ignorant Christians? Does that make sense in your world?
I am not a Christian, so my rights aren't in question here. These people who educate their children in a Christian school, have the right to do so. You don't have the right to tell them how to teach, or what they can't teach. This is more a matter of what YOU DON'T have the right to do, than my personal rights.
