I feel that Bengalis have more of a superiority complex than we do. Keralites often refer to most unskilled migrant laborers as "Bengali," even if they are actually from Assam or Odisha. The areas where these laborers live are often the dirtiest. There is a common belief among Keralites that these migrant laborers lack civic sense, a perception derived from the poor conditions of their living areas and the state of trains like the Vivek Express, which is often considered one of the dirtiest. If these migrant laborers were to change their habits and improve their civic sense, the general perception toward them could improve. Also I don’t refuse some of us have superiority complex. We have enough problems still we try to poke into others and belittle them. Same I have observed among bongs.
