Wrong. Racism is a belief based on fear and ignorance
I don't know about ignorance, but without a doubt, fear and hate.
What brings about fear and hate? Well......fear and hate is reactionary to a threat: a threat to ones lively hood, a threat to ones finances, a threat to ones family, a threat to ones environment, a threat to ones safety, a threat of some kind.
Nobody wakes up in the morning and says "I really hate Donald Trump. I didn't mind him yesterday, but I really hate him today."
In order to hate, the one(s) you hate have to had present a threat to you of some kind.
It's pretty well established that racism is hate. But to say racism is ignorance is excusing the real reason which is reactionary hate. And if there is hate, it was caused by a threat.
Bottom line is to find what the threat was that caused the hate (racism) in the first place. If you can find (and solve) that, you can eliminate all racism and hate. But unless you take that approach, you'll never solve hate or racism by name calling.
