Please do. For balance if no other reason.Ha! Don't push it unless you want me to relate some personal examples of the opposite signage as well The intolerance is largely orthogonal which is why red and blue can simultaneously think themselves largely tolerant while still thinking the other side is largely intolerant.
The urban bubble effect is Murray's theory, not mine. I was just pulling an example, because I have one.
National politics doesn't concern me much, blues come in, change what the reds did last, then make a few changes of their own. Then reds do exactly the same, so we have a bit of correction with each changing of the guard. My local elections are single party. Literally Dems against Dems, because a Rep can't pull second place. There is no changing of the guard, and no correction.
At state and higher levels, I assume most players to be partisan, but at least capable of understanding the motivation of the opposing views, even if they are dismissed. At the local level, it's echo chamber and loyalty tests, all the way down.
I understand that reds can hold office in other places, but since the blues have captured our credential mills (it seems inaccurate to call them universities any more) and most government drones are required to have credentials, I am curious about counter examples. I mean, I know there are red universities, but I doubt they are pumping out urban planners and ecology priests (which is completely different from ecologist, though they often share a credential and some of the same training) at anything like a matching pace.
It would be nice to hear stories of less dysfunction, or at least, opposing dysfunction.
