It's common sense that many American institutions are a reactions to old European institutions, and you don't need to know that history if you don't care, but if you want to have a discussion about speech in Canada (which is still part of the Commonwealth and the topic of this thread), you better have an actual idea of the way those countries function rather than applying your standards to them.

If you want to claim you have an idea whether the American reaction and discarding of old norms was actually a good idea nor not, you need to have an actual understanding about what the ideas you were discarding were actually for. Otherwise you're actually ignorant, and arrogant and that is a bad long term combination.
