But unlike what Katherine suggests, I agree with the saying that says that respect is earned, it is not a given fact.
Oh, I absolutely agree that respect must be earned. And if the people you're training with haven't earned it, you should train somewhere else.
I don't know them, I don't know you. I have no idea whether the individuals you are thinking of are or are not worthy of your respect in any objective sense. But ultimately it doesn't matter. If you don't respect them, you won't learn anything and are wasting your time.
