Racism?

Why do ppl here thinks they're fcking better than us, like CHILL DOWN GANG Me and my friends(NEPALI) just moved here and today we went to our work place and one of the lady aged between 25-30, looked well mannered and educated who has sum common sense but We were jus sitting, filling some documents minding our own business but she came and bumped in my chair(intentionally) and then mocked us saying "arey manipur walo ko uthalaye" to her co-worker like WTF is that tone? Even tho we're from manipur that doesn't make the difference that we're all human beings, DAFAQ Now don't tell me ppl from nepal are racist too cz I'm not one of them so I can't tolerate racism Also she isn't the only one who was racist towards us, This makes me wanna treat ppl rudely here even tho some ppl maybe actually nice EDIT:By the comments i can see there nice ppl too ,you guys don't have to be sorry if you're not the racist also many comments are about differences between north and south indian BUT lets not discriminate anyone and say no to verbal or physical violence
