Kurt Schlichter argues that tribalism breeds tribalism in a vicious cycle that is and will be bad for America. It is sad and worrisome to see tribalism growing on the Right in response to the Left's tribalism, but I don't really see how to de-escalate the situation. Tribalism seems to be a stable equilibrium in most of the world, so maybe we're doomed to it.
Now, the old rule for us conservatives was that businesses could do pretty much whatever they pleased, with minimal regulation, if they focused on maximizing profit and thereby rained benefits down upon society in the form of wealth and job creation. It was a good system, but, like all systems, to get benefits you have to meet certain obligations. For businesses, one obligation was to generally stay out of the cultural and political octagon. ...See, what leftists do not get is that principles are part of systems. Principles do not stand alone; they are nested within a system and together they make it function smoothly. Our system isn't some cultural cafeteria where you load up your plate with the principles you like and hard pass on the principles you don't. If you decide you don't want to play your part in the system, you shouldn't be shocked when the other participants make the same decision. "Free enterprise" means "enterprise generally free of government control," and it's stunning that the Silicon Valley people we hear are so smart don't foresee that when their "enterprise" morphs into a partisan political campaign the people on the other side of the spectrum are going to leverage their own political power in response.
