I understand what you are saying, to take a general criticism of a medium as personal offense requires a certain type of person attached to certain perspectives within that medium beyond being a fan of works in that medium. However I tend to try to not be too callous because you can treat people in good faith about their interests and they’ll sooner than later out themselves if they are the type of person you are highlighting here. Basically, the cost of giving people benefit of the doubt in this case is not too high because your doubt will be proven wrong very quickly if it is misplaced.
