I don't know -- most individuals of any political stripe won’t commit violence until things get really dire but A LOT of people were really intolerant of opposing views or at least condoned intolerance to the point where they wouldn’t stand against it even if it were done to a friend of theirs.
Think the majority of people just believe not what is true, but what is beneficial in their social and professional spheres. And when there is enough capture and detachment from real-world feedback, when they become absolutely convinced of their righteousness and the evils of those who disagree, you get violence.
If the right gets power in the institutions and starts to view itself as superior and righteous, there would be a reversal IMO. And it is interesting, as you point out, the dynamic of being in power and oppressed. Only possible in a cult.
