I am having trouble squaring the various conflicting portions of your statement.

Luminous had also posted the FHF icon with a swastika on top to YPTB

Because the Zionists currently taking potshots at the testicles of Palestinian boys for ethnic cleansing purposes are the very people Luminous was wishing death upon in reality, not Mr Kaplan.

Correct me if I am wrong, but I would expect very few of the testicle potshotters to be using the FHF icon?

You are trying to put words into the mouth of Luminous that they never said - they very clearly levied accusations against specifically the FHF, and as the picture that Rimu showed, specifically named MrKaplan as both a Zionist and a genocide apologist.

Don't forget how Luminous even outright stated that they "preemptively banned" Mr. Kaplan - i.e. not waiting for a specific event but going ahead of any such in order to enact their agenda - which now seems to be what you are claiming that Mr. Kaplan did, but both the data and the very own words of Luminous state clearly how Luminous was the instigator here.

I banned MrKaplan preemptively from !anarchymemes@anarchist.nexus, as I do anyone who displays zionist tendencies. the ban reason was for “zionism, genocide apologia”.

It is no wonder that Mr. Kaplan felt "called out", when Luminous very explicitly did such a calling out!!

But now, throughout this thread, I mostly see people blaming Mr. Kaplan, citing how he went out ahead of any specific event and preemptively enacted an action - yet rarely or only briefly acknowledging the actions of Luminous that lead directly to Mr. Kaplan's response.

i.e. Luminous of AN started a witch hunt, calling Mr. Kaplan a witch, and got defederated in return. Although, if AN truly wants to keep anything that has even remotely touched upon Zionism away from itself, then isn't being defederated from LW a good thing? Or maybe, just maybe, Luminous did not think through the full ramifications of their decision, before they unilaterally took preemptive action against several mods and even admins of other instances?
