I fear you are woefully naive here.
History teaches that every Marxist regime NEEDS and actually INSTIGATES bloodshed on a massive scale in order to solidify desperation among the populace to accept measures that under any other circumstance - would be opposed. Think Holocaust. Think Holdomor.
Demonize the opposition enemy and blame him for the misery the Marxist creates is part and parcel how they do business. The ensuing bloodbath is always welcomed and used as a catalyst to create an iron-fisted totalitarian police state, accepted by the masses.
A shooting war here is inevitable if anyone wants to attempt to hold onto what wealth and liberty they have left. Guarantee it.
It will either be that, or hordes of American Conservative Christians willingly walking to boxcars for death/re-education camps.
That too - is an historical fact under Marxist/Socialist regimes.
Think armed population. There will be no outright bloody suppression of the people unless the Marxists figure out how to take our guns. Good luck with that.
The right to gun ownership and self defense is ingrained in our culture. It can't be undone with laws, edicts, or orders. It can only be undone through force, and there isn't a force large enough to accomplish it.
