No he's 100% accurate, and it has nothing to do with the persecution (real or imagined) you have endured (sorry was that coded sexism? So hard to keep up with these things). Anyway, yes the net effect of heavy moderation to protect against offending anyone is the complete destruction of meaningful, spicy, interesting, edgy conversation that truly raises peoples consciousness of other ideas.

Just look at any board that sells it's soul to Facebook (eg: Huff Post). The conversations there used to be interesting, with honest opinions honestly expressed, but once anonymity was taken away the entire comment culture evaporated over night. Nobody says anything for fear of offending the easily offended. Or just the pragmatic concerns that your entire social circle of friends, family, work, acquaintances now has access to your every posted opinion. So you neuter your opinion down to the most banal, 'safe' expression to protect yourself. It's death to meaningful discourse.
