You describe a standard situation, which can be attributed not only to the world of poker, but to life in general. Not understanding the actions of a particular person does not mean that his actions are meaningless and wrong. They are not correct from your point of view, but who told you that your actions are truly correct? If you are trying to coerce a person that he is wrong, what do you expect other than a negative reaction? Regarding poker, why did you decide that the strategies "developed" by mathematicians are more expensive than others? If poker was possible to calculate numerically, then the meaning, interest, would have long ago lost its relevance. Note that in the situation described by you the aggressor and the dictator are you. And if you think that your strategy is much more lucrative, then it's completely unclear how many indignations from the fact that the other player plays weaker than you - rejoice at this fact. All the best to you and good luck in the game.
