Why are fujoshis generalized to be detestable and disgusting?

I like reading Bl because of the chemistry and the hardships of the characters but does that mean im a disgusting person? Because all I see when talking about fujoshi they're disgusting all that. I only fangirl in fiction characters that have good dynamics not irl because ik its disrespectful and how you will make others uncomfortable. So what I'm saying is not all fujoshis are like that and i'm feeling offended af even tho ik its not directed at me. And im sorry on behalf of all the inappropriate things they've said (even me is grossed out)
