One last toot on this thread for now. Because seriously.

Would we think it reasonable to write a blog post with the titles like "attracting not-men into open source" or "bringing non-Americans into open source" and expect women, enbies, and the entire rest of the globe to read that and feel welcome?

No, and this is no different.

The anti-pattern isn't just defining people by what they're not, but also in opposition to a dominating or overrepresented group rather than on their own merits.
