I read through the slides briefly, is it just an analysis of the current state of affairs? I can't quite tell to be honest, a lot of jargon there that's over my head, but I worry if those complaining fall into the same boat as me, in that there might not be nothing sexist there but now we can't discuss it in scientific terms now because the mere discussion point is sexist in itself.
The issue is that you can make any opinion because you have just some slides you do not know what was actually said. This institutions should apply the existing rules for this kind of complaints and this kind of issues are not for HN IMO.
