Why is this garbage here? The author's tone is flagrantly antagonistic. If this wasn't meant to be satirical, then it is almost certainly a purposeful deviation from civil and constructive discourse meant to provoke angry reactions from dissenters. It's precisely this kind of deplorable vitriol that hinders and sabotages the gender debate.
I also disagree on a purely rational level that retreating to an echo chamber can lead to anything positive: on the contrary, this is precisely how strong beliefs and emotions can fester into something malignant. This is for instance why things like the Tea Party exist - because people who shut out dissenting voices quickly become unable to empathize with alternative points of view.
