Defined as: prejudiced or prejudicial outlook, action, or treatment racial discrimination, the act, practice, or an instance of discriminating categorically rather than individually.
If you discriminate against someone who discriminate, doesn't that make you a discriminator too?
If you've ever been falsely accused of something you didn't do (or meant to do), then you might have more compassion for those who are accused. Does it hurt as much as the damage they caused? Either way, it hurts.
