There are at least 3 types of adversarial teachers:
Type 1. The anti-role model. You encounter some asshole who is assholish in specific ways that you choose to precisely reverse.
Type 2. The guru of nothingness. You trek into the wilderness, complete a road of trials, climb the holy mountain, meditate for 5 years at the guru's feet in anticipation of the secret teaching, only to be informed at the end that the guru's secret teaching is that the guru has no teaching whatsoever.
...
I feel that it's weird that my life has mostly been defined by Type 3, a little by Type 2, and I've barely had much of Type 1 at all.
I think this is mostly due to my authoritarian upbringing. I tend not to doubt the teachers and I am very very slow to develop a spiteful relationship to them.
