That’s a little harsh. Politically charged arguments are just not in the spirit of HN in dang’s opinion
Tedious, eternal flamewar is another matter. The point of HN is to have a place on the internet that isn't dominated by that.
As for "the status quo here is California liberalism", everyone thinks HN is dominated by the other side. The GP made the opposite claim (see https://news.ycombinator.com/item?id=26732300). In both cases it is imaginary.
Could well be confirmation bias on my part that this place seems to skew Californian in politics.
