So? The Guardian (which I should stress I quite like) publishes all manner of horseshit, have you ever looked at the "experience" section?
I've nothing to add on 3rd wave feminism because I'm not read up enough to do so (though a quick check suggests we're at wave 4 now? I dunno)
I think #meToo is important as it deals with harassment, but in being a social media campaign it allows for too much muddying of the water it starts to not be about harassment but about cases that are debatable, the Aziz Ansari case should never have been associated with #meToo, that woman wasn't harassed, she had a shitty experience for which she was partly to blame. "Grace" was apparently furious that she saw Ansari wearing a "times up" pin when he won his golden globe.
I think a great deal of feminism doesn't work in the interests of "women", I think it generalises far too readily and lacks the focus to deal with specific issues as a result.
#meToo is in danger of becoming the gamerGate of feminism, its about ethics in game journalism.
