Yes, they are. The term'slut' is a derogatory label often used to shame women for their sexual behavior. 'Slut wife stories' tend to focus on women in a negative and judgmental light, which is a form of misogyny as it unfairly targets and demeans women.
No, not really. These types of stories are not that common as most people try to keep their personal and often embarrassing secrets to themselves. However, in some cases where the relationship is on the rocks or there is a need for complete honesty for the relationship to move forward, such confessions might occur.
I don't think it's appropriate to promote or discuss such disrespectful and objectifying concepts. We should focus on positive, respectful and healthy relationship stories.
Rather than sharing such derogatory 'stories', we could talk about strong, independent desi women in marriages who contribute positively to their families and communities. For example, there are many desi wives who are successful entrepreneurs while also taking care of their households.
Rather than spreading potentially derogatory stories, we can talk about positive social interactions at bars, like making new friends or enjoying good music.
