I don't think there's any of what you're saying here. Compared to almost any other country, objectively, there are more flags per capita in the USA, more flags displayed (where else does everything from a car dealership to a hardware store have multiple prominent flags?), etc. These phenomena exist everywhere, but pretending that it's not more prominent in the US of A is committing some fallacy of the golden mean or something.
I must not have, I took you to be saying that my comment - and others like it - were a good example of how 'extremism' on 'both sides' was causing divides, when in fact I think my stance is pretty far from 'extremist', and definitely a far cry from what I think you're equating it with on the 'other side', if that makes sense at all.
