I don't see the distinctions made in the editorial as insulting or inaccurate to the point of irrelevance. Yes, there are generalizations. Yes, generalizations are intrinsically inaccurate. Your argument is that you don't think that the social constructs that were pointed out in the editorial are significant or relevant, and the senior editors clearly disagree. Ignoring what one's perception of reality says because it may be construed as a dangerous reinforcement of stereotype is cowardly and submissive. The senior editors seek to touch on sensitive issues, not soothe insecurity.
