Tech-bro culture expands unless it is actively resisted.
And yet, the people most effective at resisting/countering tech-bro culture are ... people who present as tech-bros, but aren't.
So, MEN, if you don't want your workplace to turn into a tech-bro club, (or want it to be less of one), you have to stop letting the tech-bro miasma roll over you.
So you, enlightened, progressive men, yes, YOU, have to take the stand. Modulo your own health.
But THIS: bros won't listen to anyone but you.
