I agree with your points overall but i feel frustrated since the argument about avoiding revolution and counterrevolution was ignored.
My apologies. Thanks for calling that out and giving me a chance to respond before going on the offense, it was not intentional but came from a but if shock at how quickly several fellow leftists that I've had good interactions with, on a leftist unity site, turned on me seemingly without missing a beat.
The argument rests on the fact that it was not some malicious murder done out of evil in the heart of a vengeful prole (though I would not blame them for it) but instead a politically motived killing caused by the material reality and historical risk monarchial heirs have proven to be time and time again. This is not dehumanising.
I agree with nearly all of that. I do, disagree on the last bit though. To my thinking "they are x, so must be killed regardless of is they have committed crimes" is dehumanization. It is placing them in a category that exempts them from fundamental human rights. I do understand the motivation and it may have ultimately been the correct choice to prevent more suffering, especially in the absence of many examples at the time of heirs of deposed rulers NOT later attempting counter-revolution. China did later show that it can be done, I think.
I still cannot not agree with that "end justifies the means" ethics approach, especially when it comes to children, who have a greater ability to change.
I don't really get the point about being jumpy by the mention of walls. For one thing it is a common refrain both on this site, and "to be put in front of the wall" or similar phrases are normal in many languages. Assuming that a left unity site would be talking of killing other leftists, strike me as a strange initial assumption.
I don't really see why anarchists would be extra hurt by the talk of walls, if you are here referring to historical conflicts. It was not as though that fighting was a one-sided affair either. The makhnovosts made use of secret police, and were in a lot of ways quite repressive. Reaction and counterreaction is not tied to a specific ideology.
This comes from historical treatment of anarchists and other leftists in the aftermath of revolutions, not directly the meme itself. Dehumanization of a group of enemies makes it easier to later dehumanize allies who don't fully agree on how to organize society. Summary execution and similar acts of violence forces those who carry it out to change in order to reduce the impact of the trauma, and is likely to cause reduction in empathy, etc. Empathy is vital. That's why I object to such a thing being a common refrain.
When it comes to Makhno and the Greens, I do philosophically have to side with the Greens - my loyalty is to common folk who have always suffered the most in every conflict in documented history. Both Red and White armies treated them as ripe for exploitation and seizure of resources, without consideration of the impact on their ability to survive. The formation of a military force for mutual defense was a necessity.
I think the idea of wanting to take protection of minorities and LGBTQ+ seriously, but then also being squeamish at the allusion or mention of violence, strikes me as incoherent as well.
The language used was too open. It wasn't "transphobes who have harmed people" or "bigots that participated in lynchings". It was simply "transphobes". Language and context matter greatly to me (possibly due to not being neurotypical), especially when talking about ending human lives. I took the meme to be akin to the monstrousity of "kill them all and let god sort them out"; alluding to indiscriminately killing without considering ignorance or psychological trauma from abuse that can be addressed.
Protecting people against reactionaires will, at times, require violence. Likewise will the changing of the system require violence.
That is to me a sad fact, but it is only grotesque because we do not consider how much violence is used every day to maintain the system as it is.
Sadly, I do agree. Non-violence alone did not win workers rights or the rights of minorities. As much as I detest it, it does appear from all evidence something that is a necessity, in the face of those that understand no other language.
