> there are too many differences for me to believe they have similar cultures There are significant differences between anglo countries but they also all have similar moral philosophy, Britain-derived legal and political systems, they’re maritime powers so have mostly compatible geopolitical dispositions, since WWI they have a history of close military cooperation, and since WWII they’ve established a stable pecking order. That’s all before considering the shared language which means they have similar ways of chopping up reality, similar myths, and a lot of contemporary cultural sharing. The differences that exist will keep them separate countries and distinct cultures but the similarities compared to other European countries let alone elsewhere are significant.
