One other point -- I think the left has effectively shifted the conversation on Israel very quickly. I think immediately following Oct 7 atrocities, public support was overwhelmingly with Israel. By raising awareness of the situation, it has now become more slanted towards "peace in Palestine." I see no reason a similar type of shift couldn't occur on any issue if a coordinated effort to discuss it and raise awareness existed.
And by doing so, it would likely cause change and or discussion by those in power.
