I don't think it's fair to assume the counterparty here is a "toxic interlocutor". Communication is hard, very hard, and engineers typically suck at it. And it is absolutely the burden of the speaker to communicate their ideas properly to the listener; it sounds like you're saying "the way I explained it is good enough for me so if you didn't get it you're an idiot". Finally, "secretly declared war on your idea"? This sounds rather overdramatic.
I'm also with you in that communication is hard and people high in industriousness and analytical can easily have a hard time with communication. Specialist have to pay attention to not forget how is it to communicate with "normal people" and speak more languages than nerdese.
Said that, I really don't think that evil has to be underestimated one bit. Ill intentions do exist.
Also, political agendas and ideological possession are brutally strong motivators for "secretly declaring war on your idea". Cancel culture is an obvious expression of that once you remove the secretive part of it and becomes overt instead of covert.
