The article itself was a bit disappointing because it focused on political issues. In my opinion the strength of HN in this regard is that it is both a "sjw cesspool" and a "haven for alt-right", as evidenced by the fact that a comment on a controversial topic can easily float near zero points while raking in both upvotes and downvotes. And even those who refer to it as "the orange site" still come back and comment. In other words, HN may be an echo chamber but it is a pretty big one with a lot of voices in it.
I'm not saying HN should allow ALL political discussion, but when technological issues inevitably and undeniably involve politics, either by influencing or being influenced, it seems a little cowardly that the general attitude of HN is "just don't discuss it" when the it in that case is core to the issue at hand, even if it happens to be political.
Ignoring the discussion of both relationships and power leads to an anemic understanding of freedom and what it takes to enable it which leaves us unbalanced and brittle as a civil society.
The exercise of this privilege is a systemic, cultural mistake and the tendency of conversations to often devolve into tribalism highlights our lack of sophistication and maturity when it comes to these topics.
