I've see comments on HN by users from incredibly diverse fields, expertise, ages, countries, etc.
If you think a specific comment in this thread reflects your blanket statement then address it directly, but overall it makes me dismiss anything you've written.
And it doesn't contribute much to the discussion

There was a recent thread with more than one person comparing cigarettes with FB. Possibly even FB being worse than cigarettes. Something that has killed millions of people. But even in that no one defended FB. They just said FB isn’t as bad as people are making it seem.
Like the OP responded, even if 100% of people aren’t the same, you can discern clear trends, behaviors, and feelings of the general commenting populace. Like we can for HN being abnormally anti-FB.
