so setup parallel schools to systematically "educate" non Christians, or is that deemed less of a core cultural identity nowawdays?

I think we all decided a long time ago that segregated schooling was a bad idea, it increased stereotyping and resentment according to studies: https://academic.oup.com/cdpers/article/10/2/81/8231636

Parallel societies have never been found to be a positive thing as far as I can tell.

As someone who was raised Christian, since when do Christians believe in equal rights for women?
