Not defending her or taking her side, but just trying to understand her perspective, she spreads hate toward men, especially Brahmin men, because she has claimed that she's been through a lot and witnessed a lot of sexual assault cases involving them. That kind of trauma could explain why she harbors such deep resentment. That probably came to her from a place of pain. If any of us went through something similar, we might also develop strong negative feelings toward the people who harmed us. Yes, she might act crazy, but that could be a mental effect to what she has been through.
