what the heck..the US should be number one or two on social conservativism. Definitely ahead of Australia and the UK. What on earth
The US' social conservativism vis a vis other Anglosphere nations are very overrated, and in fact progressive thought has massive amounts of impact on its political discourse. It also has substantially more permissive abortion laws than the UK and Australia. That being said, placing Canada as more socon than America is definitely an error, and I'll correct that.
Ok, if you mean the rate a which a country is willing to change status quo, I would agree. The US has always been the more progressive one. But socially right or left wing, it’s different still the most RW, I may have gotten confused
