The final solution...
I am now old enough to realise that humans cannot stop trying to organise other people into boxes. It's a biological thing. We are what we are.
The solution therefore is for everyone to sleep with everyone else. 9 or 10 generations later, we'll all look like generic humans and this race thing will stop being a source of injustice, prejudice and so on.
Oh hang on... what about religion, culture, political views etc...
Shit. It isn't the final solution at all!
We're doomed, I tell ye!
