Why so much hate

Hey guys I was playing valorant and my gaming name is something related to bihar cuz I'm from Bihar today my (random) teammates all of them were from West Bengal abused me for being Bihari . all kinda shit they called me I Said nothing now I feel mentally harassed. I love my country but this is something I never experienced made me feel sad why there is so much hate? What was my fault. I don't hate anyone but no one deserve this.
