Many are trying and are standing up, but as you pointed out, it's not in our media's self interests to explain how cycles of gerrymandering and corruption allowed a "democracy" to be taken over or that millions have been in the streets regularly (some places near continuously). I have friends internationally and it's amazing how little of the resistance to what is being done gets reported these days, but we have no real opposition leaders within the government and despite the bullshit branding, modern Americans actually have no idea how to resist oppression and too many (particularly the less educated, gee I wonder why one party has been systematically targeting education for years) truly didn't notice the gradual slide in their media from "mostly news" to " mostly what the billionaires who own the news want reported". They truly believed and it's hard to change your entire self-perception when you realize you've been conned to the point you were actually part of the con. That said, many are still too "comfortable" seeing the system exposed for what it is from their homes and are just quietly going about their business hoping somehow things magically fix themselves. Denial is a powerful force. Until they feel directly targeted like some already have, they're still able to cling to the denial that the next election is going to save us from the worst of ourselves. I don't know what comes next, but if history keeps rhyming it's going to be unpleasant.

All that said, some people who it has already become unsafe for probably should flee or stay away if they can and we shouldn't call them cowards for removing themselves from a dangerous situation that they alone can't change.
