Now where was I?
Clean shave the rascals, far as I can tell, is a belief that we take idiots too seriously and give them more credit, and thus seeming authority, than they deserve. For instance, if you have someone claiming to speak for all muslims/islam, and they stir up trouble or seek to cause diversion, they should be dismissed as nothing to take seriously and we shouldn't give them any attention, summed up with the yeezevee response "Clean shave the rascals".
This sounds to me like good insight Quod, I hadn't really given that one much thought but now that I think of it, it's sometimes followed by
"And put them in a zoo."
Perhaps Yez is using zoo as a metaphor for jail due to the reckless or even violent nature of the 'baboon' in question?
Or due to their genuinely primitave and dangerous manner and as a varient on our species it would be best for the general populations well being if they were kept in some form of enclosure so the rest of us could observe how truly harmful the religious brian worm can grow and become?
