Let me try to help you understand this. That vagina is attached to a girl, who has a whole identity, a name, a personality and a self- and society's respect (to a certain degree) just like you do. Let's say you are walking on the street and would you find it cool if some reasonable people address you as a "nepali cock"? LOL

Excluding Manusmriti, a lot of old Sanskrit literature that I have come across have rather derogatory portrayal of women. Do you read a lot of those?
