I am definitely arrogant. I think I have reason to be. I understand multivariable calculus, PDEs, topology, stochastics, and harmonic analysis. Most people have difficulty beyond simple algebra and I have no issues in the highest of mathematics.
Simple logical proofs like application of laws or obvious causality are obvious.
I think the issue that people have is that I treat them with little respect. We have been posting here for a long time. By we I mean the ones that I am going back and forth with. Half of them are about two people that post on multiple accounts. Most of the reason why I give little respect though is because I see a methodology based on bias rather and logic and ideology as opposed to empiricism. And when people are intentionally misleading then I am hostile.
