He's right though, zach keeps insulting people, being ignorant on purpose and just playing hurtful just because he's a superior human being. And since no one is punishing him he keeps thinking he's a superior human being and continues doing so.
Funny is that he is one of the more ignorant folks here, yet preaches differently. I have same kind of know it all in my job who thinks he knows EVERYTHING, almost 70 year old prick. While he does know his specific area of expertise, but outside of it he's really delusional and an asshole, just like zach.
