4 of the richest men in the world who own 7/10 of the most popular websites on the internet donated to and sat at The Presidents inauguration. They own the information pipeline and can literally control propaganda completely unchecked and unsupervised. Most of those gun toting freedom fighters use those platforms because it's all they know. Their family is on it, their business is on it, their news comes from it, they get their daily dopamine kicks from it.
There isn't going to be any Civil War. It's just going to be a slow rotation into what Russia currently is now. Little by little by little, hardly noticable changes, over a long enough period of time (say 4 years or so), until one day they wake up and say "Well, it was better then but there's nothing we can do about it now." and go about their day.
The next war is going to be a war of ideas and a war of messaging. We can't rely on online outreach and have to be proactive IRL spreading messages that it really is a class war. There's no better time than now, no more apparent point in history than today, it's just pulling those people away from the propaganda for them to realize it. Somehow, We The People, need to convince the Boiling Frogs.
That's part of the problem with the media circle we're in here in the U.S. - 4 of the richest American own and run 7/10 the most popular websites on the entire internet. The people who need to be reached won't leave their platform because it's all they know.
The only way to actually reach people, to actually make change, is IRL. Write letters, attend protests, invite people to protests, encourage discussion outside an online space.
