>>81979Idk, maybe it's due to the fact Scandinavia lacks cultural diversity (don't confuse with ethno-racial and genetic diversity). I'd seen a research about how it influences innovativeness.
>>81977English still have a significant germanic component, although the Insular Celts aren't the real Celts but a mixture of the local WSH-rich Bell-Beakers and the Continental Celts, thus being closer to the ancient Germanic tribes than the Celts of Central Europe, and this circumstance technically answers your question.
>Continentals are less liberal because of some genetic and ethno-racial reasonsNah, unlikely. Nothern Europeans form one genetic "continuum" or cluster so I don't think there's any deeper reasons than just history.
