So, we should just accept backwards superstition and archaic societal ideals

No, we should fight that. With words. With arguments. And not by banning clothing.

Clothing is just a symbol and the meaning changes all the time and from context to context. People who want to ban clothing are just in favor of putting pressure on other people, on forcing others to be like them. It’s despicable.

I was a teenager with very long hair in the seventies. I loved my hair, it told the world that I was a free spirit. And it was a very powerful asshole-detector. Every now and then some backwarded adult would come up to tell me I would have been sent to concentration camp under Hitler. And it was quite obvious that they wished Hitler to come back and do so again. Just for me wearing long hair.

I don’t think you believe, but I am convinced that there are quite a number of young Muslimas here in Berlin who chose to wear a headscarf to uni while their mother says "Please, don’t risk your career!"

And they say: "Mother, this scarf tells them where I'm from. And if they keep me from having a career it’s not because of the scarf, it’s because they hate who I am."

"All this pseudo-liberal, pseudo-tolerant, pseudo-feminist, pseudo-open-minded assholes, I would never detect them without that scarf! Now leave me alone, I’ve got a heritage to defend."

You’re much closer to Söder than to a humanist.
