They can go to school, not wearing those things,
It is not very different from not bringing drugs, weapons and signs inciting violence.
Please keep your strawman arguments to yourself.
Lol, I didn't mention a single thing about "drugs, weapons and signs inciting violence."
I'm squarely focused on the fact that your societies supposedly call for freedom abroad, yet deny it at home. My conclusion from all that is simple: You can't intellectually defend your own ideas, so you're using the law to snuff out opposing thought.
If your societies were intellectually strong, then you'd have no problem
convincing Muslim children to shed their past heritage and adopt the thinking and culture of their new home. But for some reason (maybe implicit racism, lack of opportunities, an insidious foreign policy, etc), you're not winning them over intellectually, so, as a result, you're forcing them to assimilate.
You're not using your own ideas to defend your ideology, but brute force. Seriously, do you fail to see what's going on here? When you tell Muslims they can't go to school (i.e., get an education, acquire skills, elevate their career prospects) because of the way they dress, you're telling them, "it's either you or your religion -- choose." That's the stick, not intellectual conviction. What's next? Forcibly taking them from their parents?
Just admit to your intellectual bankruptcy. Tell us who you truly are. We can all see it.
