You can legitimately shade a multidimensional object to a single dimension without being untrue nor even biased. The point is such a cross-cultural comparison is mostly useless. Identify themes and interests versus unobservable beliefs.

american liberals are for neoliberal markets which alone puts them to the right of their global counterparts. besides hollow support for socialized healthcare, they've put forward no meaningful reforms which would lead to it (besides the ACA which is dismantled more and more every year), they take large donations from corporate donors and are largely aligned with capital (see weakening of Dodd-Frank, Gramm-Leach-Bliley), they frequently support military interventions and large amounts of defense spending (see Iraq war, interventions in Yemen, Libya, Syria), give lipservice to pro-immigration but in action are largely anti-immigrant (see deportations under Obama and Biden), and compromise on core issues like abortion and LGBT rights. that's just a few examples.

do you have anything of substance to share, or is this what passes for intellectual discourse on HN these days?
