Why do you assume guys are never criticised in this way? HN is full of responses claiming some guy is wrong, overreacting, looking too hard for a certain type of explanation, defending against something that should be ignored, having a chip on ones shoulder re <something>, claiming blanket immunity against X, that there must be 'more history to it', etc. In all cases, these are instances of the guy being perceived as being overly emotionally involved in the subject.
