As someone from one of the regions the article claims is discriminated against, I have literally never faced discrimination on the basis of the region I'm from. And it's not like they can't tell given that my accent is quite heavy. The dialect I speak gets made fun of a lot but that's done as much by people from the region as by people from outside it. The fact that the article straight up opens with poorly done translations of online comments makes it pretty obvious that it's just another puffpiece using cherry picked examples.
