Why is racism a socially corrosive trait?

Racism is a socially corrosive trait is because we grow up empathizing with other people, with all people regardless of all people and when people are subjected to racist qualities they begin to not be empathetic toward a group of people. Not being empathetic is very degenerating of your conscience, Then people who are being treated like subordinates start to lash out and assimilate all people who are like the one person who treated them in-equally.So people who are racist create a quick downward spiral of peoples trust in people who resemble physically or mentally the people that mistreated them in the first place.

Fine it out your self
