I expect it to go the way of Germany one century ago. If conservatives make authoritarian, bloodthirsty, change too quickly they run the risk of an armed revolution and civil war.

If they go slow and calculated over the next 10-20 years, like a serial killer, they can gradually shift the overton window to where your neighbors not only vocally support murder and terrorism, but actively facilitate or engage in it. In that time they can indoctrinate Gen Alpha to be the executioners, and follow through with a level of grotesque psychopathy Gen Z and millennials were never capable of.
