there's a double rachet in activism that a lot of people really seem to miss, and slam one of the sides of it. But it's a force multiplier.
you have impolite and overton-window-pushing side
who's job is pushing the "left wing of the possible" by fighting hard for what is realistically impossible for the conditions and groups at hand but morally important.
and then there's the polite and more 'professional' (demeanor-wise) side
that capitalizes on it by now being able to present an even-more-left-for-their-role argument that now looks reasonable from the other type of person pushing the window.
(That does not mean the sort of people who weaponize "NGO politeness"/"white polite" speech to police others, but instead the people playing the other side of that political game.)
things do not work nearly as well without both.
but there's a whole lot of infighting around politeness.
If you use both in concert, you have one side moving the "tailing/'right wing' side of the left" leftward because now they seem unreasonable, and one side pushing the far side of the left further, for any given domain's far and tailing side of 'left'.
As a long term maintenance/performance/security engineer, my entire brain is designed for incremental improvement. But when I say that in activist communities they assume I mean stonewalling them, and I really don't. I need y'all to push the boundaries of the possible, and I'll be there behind you picking up the pieces and applying spackle to the holes.
and exploiting the gaps that are left in the scramble to counter them
