"retaliation" has to actually be effective. A BLM-style summer of love gets you abandoned cities and normies hating you. An Antifa-style execution gets you free bullets to the chest, courtesy of the local SWAT, and the normies hating you. A armed march down the street makes normies afraid of you, and you will absolutely have feds marching by your side.

Most importantly, an attempt on any leftist politician's life will undo all of Trump's momentum and ensure a leftist sweep where they don't even have to cheat.

You want meaningful action? Step 1 is to campaign and campaign hard. Bring the needle outside the margin of fraud. Step 2 Is to volunteer at you local elections. Be meticulous about recording everything and expose the cheat when it comes through. Gather so much evidence and blast it everywhere you can. Break into the normie sphere and get the election fraud conspiracy mainstream.

There is no instant gratification with this method. it will take many election cycles, and there can be no letting up each cycle. the boiling frog is how we got here, and the boiling frog is only way there will be any lasting change in the opposite direction. Any "shock" tactics will not have a lasting effect.
