What the reactionary centrist refuses to recognize is that centrism as a political position can only flourish by marginalizing the political fringes. In America today, the ideological fringe is represented by, on the one hand, leftist critics of the Democratic party, and on the other, supporters of authoritarian ethno-nationalism.
The former group has no political power. The latter group now controls the Republican party, which controls the national government. The GOP has been slouching toward authoritarian ethno-nationalism for more than a half century, and now it is finally all the way there.
People who long for the return of some sort of consensus centrist politics should be working toward the destruction of the Republican party. The idea of political compromise with authoritarian ethno-nationalism is not only immoral: from a pragmatic perspective it is deeply absurd.
This is where the both-siders preaching high Broderism lose their grasp on reality: They conflate powerless crazies with people who are currently running all 3 branches of government.
They things are not the same, and implying that they are is delusional.
