It's the stereotyping that really sticks out to me. It would be flagged or downvoted (justifiably!) if someone called women irrational or told homosexuals that their lifestyles should be kept private. I think the difference here is that in one case one would be inferring a belief system from membership in a non-belief-related group, while the other would be inferring a belief system from membership in a belief system. I don't think it's a double standard to treat those things differently (though there are corners of HN that get wildly out of control in either of the aforementioned cases).
