Earlier quoted context omitted.
Slashdot still exists? Anyway, yes, HN isn't just tech news, but it does seem to have a strong aversion to highly political topics because they always, always devolve into angry arguments and HN values "civility" over all else. So the parent is right IMO: this really doesn't seem to be a good place to discuss this.
It doesn't seem to usually devolve into arguments (heated exchanges), but it does tend to include debates. Just because not everyone agrees with you (or even each other) doesn't mean the topic isn't worth discussing, or that the comments are uncivil.
Maybe you haven't been paying attention, but these discussions usually do tend to devolve to incivility. Whether the topic is worth discussing is another matter; this site doesn't like uncivil discussion and tends to quickly ban people when this happens, so it makes sense that it would simply avoid these discussions altogether. These days, if you want civil political discussion, you either need to keep out people with very different opinions (so more like-minded people can discuss finer policy points instead of constantly arguing over extremely fundamental differences of worldview), or you need to have an extremely involved and active full-time moderation team to keep things civil.
