Marathi supremacists

I am sitting in a Virar train, next to me two bhaiya/Bihari girls(look underprivileged) are sitting. Two women got into the local from santacruz and asked both the girls to go near the door bc they wanted to sit. I mean?!? They politely declined saying y’all can stand there or sit as fourth sit to two of us. Listening to all of this other 2 women started nagging them. They started taunting that they stink and they are unhygienic(I disagree). In all I wanted to ask what is this Marathi supremacy they have? I being marathi myself can’t fathom why these people take their shit? Edit: I did speak up for them and told them if they have so much problem then go to another compartment, and asked the girls not to get up.
