I don't know much about burqa, but for hijab for example - and I guess the concepts would still be similar - I think a lot of people overlook the fact that in Islam at least I don't think it's just a 'piece of clothing' to cover you up etc. When having the hijab on, you are pretty much restrained from doing a lot of things Islam already taught you not to do - you can't wear the hijab and go to clubs, you can't wear it and drink in public, or even smoke it will just look weird. When you have it on, you are sort of a representation of the religion itself and its beliefs, which is why I think some women actually choose to wear it, it's the kind of lifestyle they wish to lead. I'm not saying it's any better than non-hijab wearing women, but it is a choice. So what's the big deal? It's different to what some of the people here are accustomed to, just like how wearing minimal clothing is different to theirs.
