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.

It was more an observation on what happend to the Sàmi. Which rather backs up your point really.

What I don't understand is why integration is so poor in sweden(and the netherlands) compared to the UK. Outcomes for second generation swedes immigrant are terrible in education and employment.

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