Many religious parents have issue over what they deem the "indoctrination" of their children on the acceptability of a lifestyle that they and their religion this is morally wrong. They claim that they should be able to opt their children out of these programs if they so choose - religious freedom and all. As I have stated numerous times on this blog, if religious parents have an issue with their children learning that all humans are equal and normal, then they can put their money where their mouth is and homeschool their child. Secular education is just that, secular, and must take into account the fact that people of all different races, sexual orientations, and religions are being taught. They must take into account that hatred towards any of these groups, even if it is veiled in the form of religion freedom, is unacceptable and must be something that must be taught against.
In Canada, with the Supreme Courts Egan decision, sexual orientation was labeled an analogous ground to race and gender, among others. Thus it should be treated as such, and not given any special exemptions because of religious reasons that race and gender are not given; for sexual orientation is just as normal and healthy as being a black man or being a woman.
