Found this blog post and found it had more insight into the issues around the dev and the toxicity in FOSS
Imagine you have been purposefully targeted for harassment or excluded from activities in the past due to your preferred pronouns or perceived gender. Seeing “he” with that context would likely feel excluding, which is a reason someone without an ‘agenda’ would want to see it changed.
someone … would want to see it changed
So, by definition, “someone” has their own agenda.
By definition, an agenda is “a program of things to be done or considered” which does not equate to wanting to do something. It more closely resembles a daily planner or task list.
So in as much as you and I have an “agenda” when we get out of bed, you are right, the person submitting the PR did likely have an agenda of waking up and going about their day. There isn’t a ‘woke agenda’ at play here, however, as the person I replied to seemed to imply.
