One thing I see a lot of men do that I see a _lot_ less among… pretty much any other group, is show up in other people's timelines to pick random fights.
Not merely "disagree," but "actively pick fights."
They don't seem to realize that that's what they are doing, but it is filled with the various subtle power dynamics and "monkey dance" posturing that men do elsewhere, it's just online instead.
This ties into the "my life is your academic debate or thought exercise" as well.
