Plus, none of it is relevant anyway because there are so many people poisoning the well with fake personas that are misrepresenting their political enemies for more "evidence" that their group is in the right.
(Ugh, this is bringing to mind a Reddit rabbithole where some person claimed to be ex-AHS-ingroup, and that AHS people were posting CP under fake conservative accounts on conservative boards, and then AHS people claimed that this person was never in the AHS Discords, or that they didn't exist, or the screenshots were fake, and that ACTUALLY it was conservatives posting CP under fake leftist accounts on leftist boards, and OMG HOW DO THESE PEOPLE SPEND EVEN MORE TIME ON THE INTERNET THAN ME I NEED TO STEP BACK FROM THE COMPUTER. And no, I didn't walk away feeling like I had any idea what had actually happened.)
In any case, it's my belief that all ingroups have people within them that aren't operating under their purported values (religion, politics, public servants, etc.). I also believe that the people who have the most power to effect change are the people willing to call out those within their own ingroups who are violating their group's purported principles. E.g. cops gotta call out cops, men gotta call out men, Israelis gotta call out Israelis and Palestinians gotta call out Palestinians. And yes, leftists gotta call out leftists.
I ALSO think that we need more coalition between groups with overlap on certain high-value beliefs and initiatives, and that it's easier to form that unity when people aren't using bad faith arguments to defend the more toxic members of their ingroup.
