What is the alternative which wouldn't be warped by Zionist propaganda? They literally frame everything as a call for their destruction, the OP is them framing calls to stop directly arming their genocide as such.
"BLM" was met with "white lives don't matter?"
"Defund the police" was met with "so you want crime to run rampant?"
"Abolish ice" is met with "so you want open borders?"
"From the river to the sea, Palestine will be free" is met with "so you want to genocide the Jews".
You don't combat this by simply switching language as your new choice will also be attacked in the same vein. Conceding on these fronts only serves to legitimize the framing Of the original message as extreme.
If we constantly shift to avoid their criticism, we will inevitably end at "all lives matter" and something like "Israel has a right to defend itself...but so does Palestine" (and even this would be ruthlessly attacked by Zionist propaganda).
Our goal is to transform/counter the narrative pushed from authority towards the masses (that Israel has the right to defend itself and what we are seeing is them enacting that right, the might just be going a little too far), towards what we believe (that settler colonial regimes have no such rights as they are inherently the aggressor and Palestinians deserve to live not under the boot of their oppression) not to fit inside of it.
We are to be "the vanguard", leading the masses towards a future of our making, not "the rearguard" focussed on following the masses towards wherever they march as led by borgious propaganda.
We do this by standing firm in our principles and making access to our way of understanding readily available to any who question from a position of good faith.
TLDR: They will attack and warp anything we say. We don't avoid this by constantly switching to something less radical, we fight against it via educating those willing to listen.
