I don't see the encouraging there, other than possible "medical student syndrome".

Well, they also wanted the school to teach how to have lesbian sex, which is certainly encouraging homosexuality. I'm not saying this is a bad thing though.

But to put things in context, I still think the religious education is more harmful on the average.

The idea seems to be to counter homophobic religions by forcing them to teach how lesbians have sex. I think it would be a better idea just to shut the religious schools.
