Pretty sure the entire brogrammer meme was meant tongue-in-cheek, and humor aimed directly at developers. Besides, anyone who might actually carry on in brogrammer style would soon learn the acronym CLM -- career limiting maneuver.
I might jokingly label myself a "finance douchebag" but it's more a dig at my peers than an affirmation of the industry's behavior patterns.
The culture was becoming frat-house/locker-room long before the term was coined...(Now is there a feedback loop from memes like this, who knows?)
Getting upset over a meme seems kind of pointless. Plus the internets will always win.
That said, if you do happen to meet someone who takes it seriously and lives that "life", then they're dumber than you think they are.
Notice also how there's like no "brogrammers" in here giving us their side of the story? Almost as if they don't really exist? Or if they do, it's not a life or death to them, like it appears to be to the OP?
Funny to me because I wrote a rant about how Rails was no longer fashionable and Node is more fashionable these days. A few people dissed me for paying attention to tech fashion in the first place, but now HN is all up in arms, ready to break out the pitchforks and torches, over whether or not you wear a polo shirt.
