Yes, I'm a pedant. But removing complex numbers would cut a vast swathe out of mathematics, so that's not really pedantic of me to point out. The others, as I said, bothered me less (Although the maths/math thing is a bit of a pet peeve). They were more pointed out in passing.

And I wasn't 'using my passion for anger'. No-one uses their passion for anger. Passion is what causes people to be angry in the first place. It's an emotional response rather than an intellectual one.
