As far as I know, Racism cannot be caused like an air borne disease, it cannot be sexually transmitted, it is not a gene mutation like cancer, it cannot be something ingested like in liquids, or in foods, it cannot be caused by skin contact nor is it a mental disease. Racism exists, because a person wants it, believes in it and refuses to evolve beyond it. These people are like the Horseshoe Crabs who first appeared on our planet a half billion years ago and they still exist today. They have never evolved. They look and act the same way as they did all those eons ago. I guess some segments of Humanity are like the HorseShoe Crabs. Now That’s Sad! Thanks for the excellent article, Kristen!
