Scott Alexander critiques the claim that 'America has two X-wing parties' as meaningless or misleading, urging for more precise political comparisons. Longer summary

Scott Alexander criticizes the common political trope that 'America has two left-wing parties' or 'America has two right-wing parties'. He argues that this claim is meaningless when taken as an absolute statement, as there's no objective center in politics. When considered as a relative claim, it's either false (relative to US voters) or inconsistent (relative to other countries). He suggests that people making such claims are often comparing to specific reference points like US history or OECD countries, and should explicitly state their comparisons instead of making broad, ambiguous statements.
