I think the point is that young men (at least those on the internet!) are feeling like they don't understand the lines anymore. It's a good thing that they're thinking about it! It's a failure for society if we can't help them find a way to navigate it. The conversation around consent has sort of left out how to pursue a successful sexual encounter. We should work on that. It's because we still don't like talking about sex, as a society. I'm glad we're talking about consent more now! But it's only part of the equation.
Maybe the study is shit, but it's a window into at least how some young men are feeling. The kind of young men who are most susceptible to the incel culture. If we can find ways to get men away from that path we should.
