Well then this just becomes semantics.
The struggle will not be won with PR. A fascist reactionary movement may be won with PR because PR is inherently reactionary. It focuses on the aesthetic and imaginary. The left is focussed on the systemic concrete, the aesthetic is the effect for the left, not the ideal (reversed in fascism).
I.e. Show, don't Tell.
The right can win through telling, whereas the left cannot, because the very Diegetic form of "telling" is secondary to Being.
Showing is in the concrete and bound with the act.
Trump won by telling everyone about the wall he was going to build, about the crime of blacks, blah blah.
Its in the concept of the left that they can only win through showing the revolution.
Oh yes, i'm sure FBI is putting a lot of energy into killing right wingers and Nazis.
You can try rationalize your failure to commit to the cause, but that will not make your infidelity any more justified. Do not think that things will simply remain the same if you do not act. Things will amplify, and the Nazi movement will be a major force in the US. First as Tragedy then as Farce. If we do not learn from the historical lesson then the second time round our suffering will not even have the dignified status of that, it will be a banal suffering. Like an addict that knows "just one more time" will send him hurtling back down.
Act.
If that is so, then go out and do it. Be discreet, leave no traces.
The premise that "they will be made martyrs" is so fundamentally flawed and historically disproven. Like I said before, its based on the presumption of a Hydra like enemy that can simply reproduce a clone adequate in ability to take the place of the person.
We can thank the CIA and FBI for teaching us a very valuable lesson in this regard. Martin Luther King, Malcolm X, Huey Newton, Fred Hampton, DID NOTHING FOR THE RIGHTS OF BLACKS AS MARTYRS. They were tactically amputated from the black nation of the US and so the Black Nation became crippled.
