I'm all for letting people wear whatever they want. What is the harm?
Here in Canada I've seen police officers wearing turbans. Works for me. Nude beaches? Sure thing. I've seen people in my neighborhood wearing Saudi-style niqabs and Afghan-style burqas.
Who am I to tell people what they should or shouldn't wear? How could it be my business?
I'm also for people burning the Qur'an if they so please. Or the bible, or the rainbow flag, or the national flag if that's how they want to protest. Ideas are there to be challenged.
I draw the line at threatening or harming people.
