And our brains are preconditioned to discriminate and profile.
I disagree. It's the way you've been brought up. I was brought up the same way. It's not a deficiency on our parents' part, it's just the sad, natural way people are nurtured. But I've made a conscious effort to get away from that.
Pre-conditioned? So you mean racism is inherent?
Not racism. Pre-conditioned to memory.
For example, we taste something for the first time, it is bad. Our brain makes a subconscious note that this is bad for whatever reason - be it poison, be it toxic, etc.
Or animals - you are stung by a bee, the same sort of reaction.
I'm not talking about active conditioning of humans to be racist in the sort of "good 'ol boy, let's go shoot us some ni**ers" way. I'm talking of human prejudices based on experiences and natural defense mechanisms.
