> The problem with HN for politics and economics is its decidedly Silicon Valley, libertarian and white male slant, often self-servingly pedantically amoral.
There's a cognitive bias where everybody thinks the slant they disagree with is the one that dominates this site. If you held opposite views, you'd be arguing that HN is dominated by liberals or what have you. Perhaps that's not obvious to you, but it is to us whose job it is to oversee HN as a whole. HN's archives are full of people complaining about this from all sides.
The point of view you describe (or, to be fair, caricature) does exist on HN, of course. But the community is politically divided, most claims people make about who dominates it are just a rhetorical device, i.e. to score cheap points in arguments.
