Earlier quoted context omitted.
I disagree. It’s about professionalism. Flame wars at work create a hostile environment where quiet voices are silenced. It’s the same reason HN bans political flame wars.
It’s possible to ban flame wars instead of politics. Dealing with differences of opinions (or lack thereof of this skill) is what causes flame wars. Politics is not the only thing people disagree on. Should they also ban discussion of potentially contentious improvements to the codebase? Edit: reading some of the comments below, it does also say they banned discussion of certain past decisions. It’s not just politics…
I find this statement idealistic in the US, as so many issues, political or not, are turned into good-vs-evil moral confrontation. Universal care is taking freedom from citizens. Taking vaccine is big pharma's conspiracy. Wearing masks is eroding civil rights. The left is not better. J.K Rowling is already a Nazi. Any Trump supporter should be hunted and punished. Questioning Faucci is anti-science. Questioning Biden is supporting Trump. Asking a person not to graffiti on my house means losing my job for opposing the right movement. And how much hate did Bari Weiss get from her staff for an editorial decision?
