Education is the only cure against injustice.
People only do things like this because they are ingroance, stupid, and weak. However, if they learned to educate themselves and gained some critical thinking skills they will see how flawed that POV is.
As much as logic can be used for good, it can also be used for evil. Pick any topic you hold near and dear to your heart. Read a book about logical and critical thinking. Learn just how easy it is to make a counter-argument to anything.
We could all be better educated and still have the same old fights, just in more flowery language. Most of our elected officials are college grads after all!
A better cure for injustice is empathy. When you take a moment to consider life in someone else's shoes, you understand them a bit better and are probably less likely to want to hurt them. It's not a complete cure, because there's always going to be someone that STILL wants to do harm to a person, but it's a pause and then action, rather than all the knee-jerk violence. I don't know how one goes about teaching empathy though.
