Seriously, this is the best you came up with? Technically being Muslim isn't banned in China either. Preventing people from harmlessly practicing their religion is also against freedom of religion.
Who is preventing Muslims to practice their religion?
Hijab is part of Islam so... There's your answer.
Enforcing a sexist, misogynistic, ancient ideal that women need to cover their body for men to not to be tempted is in no way “harmless”
Miss me with your white savior bullshit, Muslim women are perfectly capable of thinking for themselves, so when they ask for hijab to be banned you can say that.
