It's not about changing the asshole's behavior, per se, it's about changing the response of Jim, random third party in the meeting where Bob says he's sitting across from Katie so he can ogle her tits from:
"Katie, lighten up"
to
"Bob, stop being such a creepy fuck. It's unacceptable".
I think the people who pay attention to things like your blog post are the people who are already sympathetic.
It's like if you wrote a guide about "How To Not Be An Asshole", assholes would probably not read it.
