The only things you know are that you (a) can't disprove what I said but that (b) you also don't find enough through which to prove it. The latter can be caused by me spouting nonsense, but it can also be caused by you not understanding what I said well enough. Nevertheless, you make judgements and indictments without admitting that you don't actually have any intention to (a) check and improve your understanding of what I said and (b) check the veracity of what I said.

In other words, you're acting on the basis of what you do not know and informing others of your feelings. That tells me all I need to know about your ability to judge toxicity from teaching. It's never easy for people to learn something new. But you are only aware of how it feels to you, and you don't have the ability to distinguish whether it makes you change for the better or worse.
