Shame on Khalid Mohammed for portraying Muslims in such a bad light!

Khalid Mohammed (I guess he must be a Muslim) has portrayed the lead character Tehzeeb (played by Urmila Matondkar) who is a Muslim in the movie as so westernized. The clothes she wears were so immodest and her lifestyle was so westernized as well. She didn't even look like a Muslim. I mean, Khalid could have portrayed her as a Hindu girl. There's nothing wrong with that! But why give so much wrong impression about Muslims to the audience? In one scene, Khalid shows Arjun Rampal praying Salah in an improper way. Why Khalid why? You're a Muslim and you should have known better.
