Well, I'd normally not object BUT the school brought in a sampling of religious groups to show what they taught on the subject. They managed to find religious spokespersons that ONLY ACCEPTED HOMOSEXUALITY.
Do you have any idea how hard it is to accidentally come up with that result?
Conclusion. It wasn't an accident that they came up with that result. They were INTENTIONALLY foisting a minor, rare religious viewpoint upon public school children.
Violation of integrity; probably a violation of law.
So you're saying that these religious groups would accept only homosexuality, and not even heterosexuality? Where would you find such people? Major media newsrooms?
