this could help, but you could go even further. Instead of "you're being an asshole" you could say "this is an asshole thing to do, you probably shouldn't do this" or something like that which dissociates the person from it very aggressively.

I agree that it’s up to us to redefine what healthy masculinity should be, there’s a lot of redefining to do in general… And the value of information cannot be overstated in these cases, because examples of how not to do it can be the perfect points with which to define to-dos!

yeah. It's going to be a big change socially.
