So you're saying he suffers from "know-it-all-ism"...
That's not a good thing in my books...
A "know-it-all" by definition is someone that pretends to know everything but doesn't, and then gives excuses when you provide facts that he has no answers for...ie.. they're f**king annoying.
I'm also a big fan of people that actually find out stuff for themselves from educated, well spoken people that take the time to explain every nuance of what they are doing and why they do it, rather than those that are judgemental and jump to conclusions.
But eh, I get what you were trying to say now.
