Think about it?

Don't be naive, people will always find a reason to hate each other.
If it wasn't skin color, it would be smell, or voice pitch, or straight vs curly hair, or height, etc. etc.

So true that's the point I'm making you wouldn't see colours if your blind only senses touch smells the We would not even know what colour is because we have never seen it if someone said that's blue you would not know what blue is ect ect

And if everyone was born blind we would help each other more and band together

My point is if humans couldn't segregate and discriminate against each other by the differences they see, they'd discriminate against each other by the differences they could hear, or smell, or touch more likely than work together.

Your right maybe that's just or human nature built in side us over generations we are still animals in our DNA you have to take life with the good and the evil. Positive and the negative to forces in the world cancelling each other out to balance the universe out good Over Evil +Vs- G.O.D -takeaway the a letter O too the word good you get GOD +the letter D to the word Evil you get Devil maybe is in our fate and nature to hate each other .

We're just tribal animals in a modern world.

You know, people sound their race too.
