The research contradicts you (https://en.wikipedia.org/wiki/Gender-equality_paradox).
>We have tons of data on that, including experiments where using a feminine or masculine name changes how contributions are received.
Your link is to reporting of a viral anecdote shared by an editor for a movie review site. It's also about how clients responded, not coworkers.
Aside from the "experiment" being N=1, easily confounded by any number of factors (such as the simple fact that, from the client's perspective, a supposedly troublesome contact was being replaced at all), and at least partially an excuse for Mr. Schneider to complain publicly about his boss, all of this clearly has nothing to do with "STEM", let alone programming. Historically it has been common in programming circles to receive contributions under pseudonyms (or, for that matter, first-initial-plus-last-name usernames) that don't disclose gender.
The argument you present here is simply not intellectually honest (and I have seen very similar arguments countless times over the years).
