In my mind, it's far less important that we try to address these topics "without emotion" (whatever that means) and instead focus on cultivating respect and curiosity and assuming good faith. This is a bit more congruous with the spirit of the site.
There's another Western cultural aspiration involving an impossible decoupling, probably more common in American culture than European, which is to depersonalize politics. But politics is about people, and some people are much less immediately affected by political and social issues than others -- there's usually a great many layers of indirection between the articulation of a regressive point of view or support for a particular law or politician, and e.g. a minority being squished out of tech or a parent who was a victim of a hate crime or a queer person's suicide. There are probably especially many layers of indirection when it comes to a lot of tech workers, given the demographics.
In any case, when discussing politics and issues of class and race it's important to recognize that you're not talking about something abstract, but people, and their loved ones and families. Given that, it's hardly a level playing field if we start with the expectation that folks will leave emotion at the door
If some people are prone to lack of control, that implies little for individuals.
Yes some of us can reason.
And I feel that's a comment issue more than a topic issue, so it's odd that HN punishes a post topic for a commenting issue.
If you act out on the anger or resentment, no one wins anything. At that moment, it's a good idea to make an effort to argue from a purely logical standpoint instead of just insulting the person you're arguing with. I think that's what most people mean when they say they want to discuss "without emotion".
I imagine people come here preceisly because they are that niche that wants to deep dive into those specific technical topics. I wouldn't be surprised if a topic like that could get 100 comments here and barely get a dozen comments on reddit/4chan/etc.
