I think it would make for an encouraging change, for a few reasons. Firstly, I’m an up-winger, so of course I’m in favor of this ideological revolution. Second, it wouldn’t really be a revolution, but more a reversion to the mean: the up-down distinction has historically been more practically relevant than the left-right distinction. Third, an up-down distinction would redound to the benefit of upwingers. Downwingers are present on both the left and the right, but are more sound than fury—refocusing the debate toward upwinger varieties on the right and the left would further marginalize the opponents of progress.
