I like how John is complaining that other dude's comments aren't giving value, despite each one being fairly thought out (by Twitter standards) and fairly polite. He's not even really challenging John or anything, agreeing that it's a problem, but pointing out/asking a seemingly genuine opinion on how to deal with the problem.
Meanwhile, one of John's post is just "NAZIS" and "Ban Nazi's". Which he then follows up with a passive aggressive insult, the nerve to call himself a professional, then questioning what value the other person is having. Really, the most surprising thing is John didn't accuse the other dude of mansplaining or do a "as a woman in the tech industry" style post.
