Earlier quoted context omitted.
> I have never seen it happen in my 10 years in open source Seems like a very generous reading of what the person I'm specifically responding to said
I don’t see how you can possibly think that. Saying that you’ve never experienced something is not a claim that no one has ever experienced that thing. Mine is not a generous interpretation, but rather I’m not going out of my way to infer some nefarious subtext.
If you are a woman or black or ... you will very likely experience sexism or racism. You will probably also see more, because you are used to identifying it.
If you say "a third [1] of the people in this group experience a bad thing" I would say that's pretty wide-spread.
The OP was specifically saying "it's not widespread, I've never seen it" [2]
I'm not trying to claim there's a nefarious subtext. I'm not saying the op is sexist or racist. I'm just trying to point out that a lot of people experience this, and one of the stated goals of CoCs in open source or at conferences is to help combat it. I think that's a good thing, and while you or perhaps others have pointed out that a community could combat such negative behavior without a CoC, the CoC does give some indication of how such behavior will be dealt with (before I join the community/attend the conference), which can increase my confidence recommending a conference or increase someone else's confidence attending (or participating in an open source community etc)

[2] not a real quote so please correct me if it's way off, I'm being lazy
Also, I know they were referring to open source - maybe they've seen workplace sexism etc and were specifically excluding that. In that case I'm definitely misquoting and apologize
