The Misunderstood Role of the Hijab

A conversation with a professo recently made me realize something that I'd always known and believed but hadn't yet discovered for myself: When you wear a hijab, you are expected to be abnormal.

A hijabi girl is not allowed to smoke, drink, talk to non-related males; she must walk properly, dress properly, and be perfect and "modest" (whatever this term means) in every other way. But why? Why does she have to be burdened with all of this? If she would do these things without the hijab on, why can't she do them with the hijab on, too? People often say, "What's worse is when a hijabi smokes -- or wears tight jeans or hugs males or laughs loudly in public," etc. But why deny her these things just because her hair is covered? And why are we even assuming that she is wearing the hijab out of personal choice? Why are we ever shocked when we see a hijabi girl holding a boy's hand (a boy who's not her husband)? If she smokes, why is she not expected to smoke if she has the hijab on, for example? Or if she holds her partner's hand in public, why should she be forbidden from holding it in public with the hijab on? 

Of  course, like everything else, this can be viewed in different ways, both negative and positive. One way could be that when a female wears the hijab, she starts to represent not only Islam but all Muslims. Hence, she must behave like an ideal Muslim female -- or else. Another way could be that wearing the hijab, deemed a symbol of modesty and virtue, means that she is striving to become a better Muslim, which implies that she must avoid everything that she is expected to avoid. As a result, since smoking is not something that "good girls" do, hijabi girls, who are normally seen as "good girls," should not smoke. If a female does not wear the hijab, however, then she may do so, since she is not laden with the burden of representing an entire faith, or over a billion people worldwide.

None of this is to suggest that I am calling for hijabi women to start drinking, smoking, dating, wearing indecent clothing, misbehaving, etc. But why such serious expectations with one choice?
