It seems to me that some valuable things are said in ALL of the above comments.
Particularly, a key point above - "political action should be about changing the system, creating the world we want" - which implies, correctly, going far beyond "protest" to the deliberate formation of leadership and mobilisation to overthrow the capitalist ruling class.
When it comes to describing the process of degeneration into crisis and warmongering in the USA from Reagan onwards and the current Washington administration, I think if anything the term "fascism" is underused.
People get into too many scholastic niceties about what type of fascist, what uniform, what boots, what flags etc - rather than seeing fascism as more broadly what spews out of capitalism in breakdown in the advanced metropolitan countries, and what gets done on a day-to-day basis in oppressed countries by death squads or by the CIA, invasions, bombings, torture, assassinations, sanctions, lying media and criminally corrupt stooge governments.
It is hardly surprising given the activities of white supremacists, state viciousness and the wholesale racist manipulation of the electoral process in the USA that terms like "white violence" get thrown about by African-Americans and other minorities. But it is unhelpfully divisive, as is seeing the struggle as black vs white (or North World vs South World).
If the US ruling class and their state are going to be overthrown it will take great levels of working class unity, great scientific Leninist leadership and the convinced masses seizing on the openings to revolution provided by the collapse of the "free world" "freedom n democracy" circus (possibly from military defeats more shattering than Vietnam in the 1960s).
But there should indeed be far greater clarity that REVOLUTIONARY violence keeps being shown to be NECESSARY by the actions of the decaying monopoly-capitalist ruling class through its police-state violence, vile media, and horrific international warmongering as seen in the devastation of the Middle East and support for Saudi and Zionist Nazi aggression.
And here the first "academic" comment is surely useful for describing the difficulties that students, workers, trade unionists and academics (even!) are facing when they want to confront some US state injustice but find they are attacked either physically or in the media for "dangerous and illegal violence".
Doesn't this put a premium on understanding what's really necessary, so workers and students don't face years in prison or getting their skulls broken for very little gain?
Students and workers should not be asked to throw themselves under the bus for "protest" alone.
Instead, a full perspective of the need for the socialist revolution needs to be put in front of everyone, and the nature of world history as nothing but a series of revolutions, up to the current foul decay of the monopoly-capitalist system into global war (WW1 & 2) and now a renewed slide to world war, with the destruction of huge areas of the Middle East, killing hundreds of thousands, as just a starting point.
Trump's Mussolini-style bombast is certainly a pointer to the US Empire's sick plans for the world, as it tries to stay "top dog" in capitalism. But German, French, Austrian, British, Japanese warmongering belligerence is spewing up too, unmistakably.
As with Brexit, where British workers are "apparently" drifting racist and to the right, the white working class in America "apparently" remain backward in their politics. But this is hardly surprising.
They've all had years of racist, jingoistic and class collaborating Labour party, Democrat, trade-unionist, Trot and revisionist politics rammed down their throats. No one is explaining the capitalist crisis to them properly, and therefore COMMON (black, white, Latino, man, woman) action to end all the injustices they experience is denied them.
It's time to counter all the divisive, reformist nonsense with the CORRECT (Marxist revolutionary) politics of Leninism.
