I think the very first rule of life is to live. If someone helps you live when otherwise you're going to die, you should tolerate more of his weirdness. If someone helps you live better when otherwise you're going to be quite miserable, you should also be more tolerant. I think this is the logic of meritocracy, and the logic behind capitalism.

You either believe in capitalism and thus meritocracy as its twin, or neither. Why do capitalists get to take away so much profit, and why should we award patents to inventors, if we don't reward those with "merit"?
