I'm an agnostic. You talk about how "backwards" various things are. You talk about freedom. Yet you are the one imposing dress code.
To make a parallel to the world of tech, it's a lot like those "cool startups" where "we don't make you wear a suit & tie", but if you show up without jeans people look down on you.
Let people dress however the hell they want already. I don't care if you're wearing a cross necklace and I certainly don't care if you're wearing a giant shirt & cap with a picture of jesus and "I LOVE JESUS" written on the back. And you comparing a traditional clothing to a crusader's robe "that killed hundreds of thousands" is... honestly the most repulsive thing I've read on HN this month.
Our women are free, yes. They're free to dress however they want. And if they want to cover themselves head to toe, they're free to do so. Muslim women are especially modest, and see their hair as private. Some women see their legs as private - we're not banning stockings.
You don't get to talk about freedom any more than americans do when they parade around bombing countries to "export their freedom", as you so nicely put it.
