Obnoxious and arrogant is in the eye of the beholder...
This is, for all practical purposes, false. "Obnoxious" and "arrogant" are not properties like "blue" or "spherical" or "rumbling" that correspond to objective phenomena independent of social context.
If you say the ball is spherical and everyone else around you says the ball is cubic, you are almost certainly correct despite being a minority of one.
If everyone around you says that you are obnoxious and arrogant, then you are, in fact, obnoxious and arrogant, even if you beg to difer.
Iksorod and I made a Google doc of intro-level training materials for rationality / critical thinking. We'll keep adding to it as we find more stuff. Please comment with your own additions.
