More like suppress speech and freedom the way Stalin did, not to mention 2nd amendment suppression to the point that ONLY Democrats have guns. . . then there is the old Stalinesque tactic of starving groups that he didn’t like. . . that means US, fellow Christians.
Good luck with that.
I predict the left will continue to do more of a slow boiling frog approach to control Christians a little more than an abrupt approach. They don't want to stir up the young adults to fight back against the real fascists (i.e. they don't want more young adult men becoming Christians and attending church and young adults setting up more TPUSA chapters like what's happening now). Think creeping dhimmi status instead of concentration camps...at least for now.
I also predict that the Dims will drop the "nationalists" from their new bogeyman catchphrase "Christian nationalist". Soon it'll be just "Christians" that they'll blame as the bogeyman. Much like they quit saying "white supremacist groups" and now blame whites in general -- and they quit saying "male chauvinist pigs" and now just demonize men in general (at least straight men). But again, I don't see them calling anytime soon for all Christians to be rounded up. More like a constant demonization of Christians to make it harder and harder to be accepted in professional jobs or "polite" society if openly stating faith in Jesus.
I do, however, see a lot of "oops" problems in areas in general in things the Dims over-regulate. Much like in tyrannical countries the regions that often criticize the govt have problems, just by chance I'm sure, with the power grid being dependable in those areas. Or only a few gas stations can get permits to sell in those areas, etc. I can see the Dims implementing that kind of thing more against areas that don't vote Dim (and/or areas that are openly evangelical).
Which, by the way, is one of the reasons I started experimenting with decentralized solar and swapped out one of our old gas cars for an EV. What I have going on is not enough to be entirely off grid (it doesn't help survive a Mad Max dystopian scenario). But with only 20% of my power having to be pulled from the grid, it would greatly reduce the slow boiling effect of the Dims pressing my wife and me to bow to the Dims' cult. (Particularly since the Dims have made it clear that their warmageddon doomsday cult energy policies are a favorite way for them to try to control the masses. Thus, those polices impact us directly only 1/5th as much.) I figured it was time for at least one of us American Christians to begin experimenting how to give us Christians a cushion against that tactic.
