They didn't suggest men couldn't understand, they actually offered a way to help foster understanding by creating the false profile. The ones who won't understand are those who make no effort to understand, and that's quite reasonable to say.

A woman's online safety relative to other spaces also misses the point about their online spaces being less safe than those of men; the suggestion wasn't that online spaces are the absolute most dangerous spaces for them.

That said I would raise the point of how easy it is to dehumanise people online and how easy it is to quickly gather various data like work addresses etc.
