I'm confused by this comment.
(1) The paper contains the statistical analysis, and it's a significant difference. It could be noise, but that's unlikely (because statistics).
(2) This isn't about the gaming community. The discussion clearly hopes to apply this principle (that misogyny is often an attempt to compensate for some social threat by attacking another group) to other settings. It's just a lot easier to mine for misogynistic comments in a game setting than elsewhere.
(3) This paper actually is kinder to gamers than 2013 publication the data came from. It's not about how gamers are all misogynists. It's about how gamers who are bad at games are more misogynistic than gamers who are good at games, because they're insecure.
