The abaya isn't just a headscarf, though. It only leaves the face uncovered and I have seen kids who also additionally cover parts of their face with it.

I just googled it and it's literally a fucking dress. Sure it's often combined with a headscarf or (I guess this is what most people have a problem with, a Niqab), but how can you tell women (and often also men) not to wear a dress?

You're right about the homeschooling (not so much on the private schools, but that's not really relevant to the point), but that doesn't stop religious radicals to pull their kids from schools so they can better indoctrinate the kids themselves. This was a common problem during the pandemic, where parents who didn't agree with the state policies pulled their kids from school and it's a common problem in counties where homeschooling is legal (like the US), where strictly religious or conservative parents pull their kids from school because they're learning about gender identity and receive sex education.

Personally I think we need to do more to push back against conservatism, not less.

Something we agree on for once. I'm not religious and I hate to see religion being pushed on to kids. However, I'm a all a strong believer in democracy and the freedoms it gives us. That dies mean though, that we have responsibilities as well. You can't pick and chose when to apply the rules we set up for a better world and when not to. The EU has committed itself to the "EU Guidelines on the promotion and protection of freedom of religion or belief" and we can't throw that out of the window, because we don't like how Muslim people dress.
