I don't know, I think it might be more beneficial for those who can accurately observe the political cirque de jour in whatever locale (opposed to being caught up in it) to engage amongst themselves, than trying engage with those who belief systems are dominated by a particular local/flavor (unless such engagement is exploiting another particulars beliefs against another for some gain).

Said another way a bit more reductionist, it seems that any engagement between CNN vs Fox types is rather marginal (for expected outcomes), vs playing both sides and exploiting the cognitive dissonance/norms differential between the two.

I think this chapter in human nature could be described as a conundrum that arises from the allegory of the cave.
