Nothing astonishing about it. Religion is a private affair. If you're in capacity of an agent of government, no matter what level, neutrality is a must.
Many Jewish women wear wigs for the same reason as many Muslim women wear headscarves. Are they going to ban wigs for everyone, or just women who happen to be Jewish?
I'm an atheist, am I allowed to wear a head scarf or is it only banned if it means something to me?
Can I wear a cross if I'm into Gothic fashion, as long as I swear I don't believe in Christ?
Not saying you're wrong, but could you provide a source or more information for the claim that jewism women wear wigs for religious reasons?
Thank you.
