I don't think there's any pre-Southern Strategy republicans left. They're pretty much entirely onboard with nationalist white supremacy. Yes, there are undercurrents of racism left in the Democrat party, but it's the far softer racism of lowered expectations. The "you can't take care of yourself or make your own decisions" kind.
But in a contest of the White Man's Burden vs The Final Solution, it's a pretty easy call which is more abhorrent... which one is addressable through civil methods, and which probably isn't.
As for Roe, it's been a dividing lynchpin since it was first handed down, as is often the case with legislation from the bench. The whole weakness of RvW was that it was not passed as law, it was decided by the supreme court. This is how democrats get policy enacted that they know won't actually make it through congress (it's also their primary method of trying to undermine the 2nd amendment without repealing it, because they know they have never had the votes), and they're learning that this is a sword that cuts both ways now that ultraconservatives control the supreme court. Every waking moment has been one side seeking to enshrine RvW, with the other endlessly attempting to undermine it. Even I used to joke 20-25 years ago how "No democrat will confirm any judge who doesn't perform a partial-birth abortion live on the Senate Floor." Somewhere they seemed to stop sticking to that particular set of guns.
I tend to think the Obama era made them complacent, while it galvanized and radicalized the reactionaries. The democrats, high off the heady scent of a black president, thought they'd "finally won," and could relax and take their victory lap. Meanwhile the republicans decided it was the point at which the mask of civility could be completely discarded and that never again would they engage in parliamentary democracy in good faith until all opposition to their supremacy had been eradicated.
And like I said before... aside from young firebrands like AOC and the rest of "The Squad," they will continue to hold meetings and breakout sessions where they were make points of order and issue statements of disappointment and denunciation until the boots are in the hall outside the door. After all, not only would it be uncouth, every democrat politician of any influence and standing is still too uncomfortable with the idea of those in power being held accountable for their actions to really put the energy behind saving the republic that is required. They would rather hope everything will work itself out than upset the apple cart, and possibly bring their own sins to light - and have them used against them.
Jan 6th was practice. It was our beer hall putsch. It did not fail, it was merely practice. Nobody of consequence has been held accountable for it, and when the midterms swing massively away from the democrats in 5 short months, that will be the end of it. Not only will republicans be untethered, all their street-level thugs and cultists will be emboldened to violence as never before.
