And yet you are treating their comment like a "real problem"... you're the one crusading, they just gently and non-confrontationally made a suggestion. You could have just passed on by if you didn't agree with their suggestion, but you turned it into a crusade against them. To the observer, you are in fact the one acting like a "snowflake" fired up (dare I say "triggered") by their actually quite gentle suggestion, in which they make it clear that they weren't accusing anyone of ill-intent.
Do you think your annoyance and anger at their suggestion is a "real problem" or a "snowflake problem"? If you don't think it matters that much if someone says "man year" or "person year" (you said it wasn't a "real problem"), why is the suggestion to do either way so triggering to you? Do you think it might be more in line with how worthy of your annoyance it is to see someone suggest "person year" (maybe not worth that much annoyance in the grand scheme of thing when we have 'real problems'?) to reflect on your own about why their suggestion to say "person year" made you so angry and upset, without needing to reply on HN and turn it into a crusade?
My annoyance is that it has absolutely no relevance and adds nothing to the discussion regarding the story/post. It's just noise, which begets noise (my response) and so on. Let's talk about tech.
If left alone, there would have been nothing distracting about that short and explicitly non-accusatory comment, but you were triggered and chose to build a crusade around how you don't want to see certain kinds of comments on HN. You seem to have trouble handling the fact that some people have different opinions than you, about what comments are worth making. Very snowflake problem.
Sounds like you have a problem handling the fact that some people are tired of the bellyaching every time someone uses a common term in which it is not meant in a derogatory way.
You understand that there are millions of women who are victims of abuse, sidelined or disregarded by society, and constantly repressed because of sexism, right?
Losing your job is a temporary problem for most people. Sexism, like the kind that is baked right into our language, is an inescapable daily struggle for many women.
We have the capacity to think about both women's rights and the recently unemployed at the same time. It's frankly sad that you can't look deeply enough at this issue to see it as more than a problem of "grammar preferences".
Once again, none of this is relevant to the post regarding Uber's layoffs unless they're somehow disproportionately laying off more women than men can it be even considered remotely relevant.
I disagree with such a compartmentalized way of thinking about these issues, where it's inappropriate to discuss gendered language when it comes up in some other context. That's often the only effective opportunity to address this kind of problem. A comment about the use of gendered language is relevant in response to a comment that uses arguably gendered language.
