I wouldn't try to address the sl ut side because frankly that mentality doesn't even deserve any kind of acknowledgement.
But the term doormat is the reflection of people's anger when they watch a woman with so much potential allowing a man, who does not respect her emotions, walk all over her. And it has stemmed from the times we find ourselves in. It is too freaking modern to label the toxic bond of sidnaaz as romance.
Acceping the multi dimensional personality of Shehnaaz is new to me as well. Previously my feelings were along similar lines too. But I would also say, that it is only recently that Shehnaaz has voiced her feelings and 'lack of respect when it comes to one man' concept so openly. Either it was not telecasted, or she was confused herself- but her opinions were not easy to decipher. Maybe because there were too many people in the house
Currently, I cannot put her in a box. She is who she is, and Shehnaaz is quite proud of the fact as well. This confidence stands out when she speaks.
Also, choosing between the two extremes is a cultural issue. Not many are able to appreciate the nuances. I am sure there will be many who will judge her once she steps out. So will hope that she keeps this no f*cks given attitude in future as well.
