There's a little bit of that on HN. Not more than other places. HN is certainly not "Digg."

On the other hand, if you attack the big SWPL shibboleths (human neurological uniformity, homosexuality as mirror-heterosexuality), you tend to get stomped on. I've known hard-core Marxists who are less fanatic about believing what they're supposed to believe about this sort of thing.

I generally assume it's because the worldview of the average HNer is not even a little bit informed by biology. Just look at the uncomprehending awe that your average hacker holds the for the term "neural network" or "genetic algorithm."
