Rajput and Brahmin supremacy

Many people from other religion or region talk shit about Brahmin Rajput people or talk shit about religion in our country. I think it's only because of bad people like kareena-anushka because of whom many people think all women are shit. <br><br>Why these people who are clearly jealous don't understand that one person is bad it doesn't mean the whole caste is bad. From where does apna caste supremacy come from?
