Why hate Bahun / Chhetri

I have heard so many of mangolians only them talking shit about bahun and chhetri like why?? Is there any specific reason for hate?? Heard them saying "desh bechera khaye" if you are politically backwarded that's not because of us.. Try hard get in position and then aafu le pani becha desh. I don't think desh banaunu thyo bhane hate suru gartheu. And if we talk shit back you guys cant digest it. And still any other reason to hate us ki eauta mangolian le garyo bhane arko le ni without reason garnai parne hunxa so you guys started doing it 🐏??
