I found it pretty disappointing to be honest, which serves me right for going along to have my prejudices polished.
I have a visceral loathing of tabloid-stupid genetic determinism which I see as a throwback to Herbert Spencer's loathsome social Darwinism, and so does Rob Newman.
It's just not very funny.
He is fighting the good fight though.
The wisest thing in the world is to cry out before you are hurt. It is no good to cry out after you are hurt; especially after you are mortally hurt. People talk about the impatience of the populace; but sound historians know that most tyrannies have been possible because men moved too late. It is often essential to resist a tyranny before it exists.
