I think stuff like
is fine because 1. It's a Nazi and 2. It's not a real person. I think
is fine because it was a bunch of partisans getting retribution during wartime. They had no time or resources for a fair trial and they knew the people they executed anyway, so the evidence was pretty clear.
I think the reason that image crosses my line is because it depicts a traumatic event that happened to actual people, and some of those people didn't really have the agency to do anything else. I'm not sad the Romanovs are dead, and I think the overthrow and owning of a doofus failson named Nicky is something that should be celebrated, but I just don't think that justifies mocking people in their last moments. Had things been different then some of them might've gotten the Puyi treatment, it's sad that that wasn't possible. I'm not losing any sleep over it - they are caviar as their people were starving and dying at the front - but that doesn't mean I think it should be turned into an object of ridicule.
It reeks of aesthetic communism. Like some chuds support the USSR because they think the holodomor was real and they think it was a good thing. They just like cool mosin nagant, human wave death machine, lol kill people. That's what that image reeks of.
