Nope, he just means that hubski has a culture/community that doesn't have the problems outlined in the article, namely a bitterness/aggression towards women.
I thought you were replying to me, and then I noticed that my comment was among the most recent... Anyway to expand on what seems like a crap answer. Say you're a female on Reddit (doesn't matter where) and see how quickly your inbox fills up. I did this once as an experiment, and gave it like 2 weeks before I shut down that account. Anyway what happened was that it was almost a non stop continious inflow of men sending cock selfies and (what I understood to be) sexually harrassing messages. Which shows I think, the aggression to women that Reddit has. (Among the messages that were received were a lot of hate mail... So there's that too.)
