DNA: Why uproar over hijab again?

A teacher in a private law college in Kolkata suddenly started wearing hijab. When asked, she cited Islamic beliefs. Professor Sanjeeda Kader of this law college has been teaching students studying law for a long time. During this time, she kept coming to teach students in formal clothes like a professor. But suddenly after the end of Ramzan this year, she started coming to college wearing hijab. When the college administration raised objection, she resigned.
