I mostly agree but the Brendan Eich firing and the dongle joke kerfuffle are counterfactuals. Or, taking a group example instead of individuals, "brogrammers".

I think you can be unpopular or stick out in a lot of ways and still be successful, but I don't think it's as simple as come-as-you-are. You'll do fine (I'm sure Eich is personally fine) but you can easily hit some challenges along the way.
