Redeclaring what for aeons was wanted and usefull behaviour as sickness? Yes, your ancestors wanted that hobo under the bridge.

He made a excellent scout, he was fearless and his pattern search skills where superior to yours. He kept you fed, he kept you save, until he was no longer useful. If it has no skin colour, and the difference is all in the head- one could obviously not term this a race. It has to be visual, to be a acceptable concept.

Look at him, going the way, you will go, once your usefullness has ended.
