Suddenly seeing more hexbear posts. Did we re-federate with them?

you're dodging the point so blatantly here. Was it inherently right wing to use violence to force the confederates to free their slaves and disband their secessionist army, and then to use political repression to interfere, however ineffectively, with southern efforts to keep their way of life alive after the war. Was the authoritarian means they used – warfare and political repression — inherently right wing, even though the objective was to free enslaved people.

yes, I know that many in the union were racist too, and grant and sherman participated in the genocides of american indian tribes, and all of that. that's not what we're talking about though, we're talking about authoritarianism, and whether authoritarianism specifically is what makes something right wing.
