Should we do anything about racist people?

Its funny when you come across racist people; truly, the best way is to ignore their ignorance at a personal level. Through your positive inclinations and actions the people out there, the people who are not ignorant will see you for who you are and of course they see these racists for who they are. That said, these tiny things do stir you up a little bit on the inside but to retaliate should never be the solution. It might be a platitute but it doesnt make it less true "Two wrongs dont make a right"
