the issue isn't if JK is a swastika waving nazi - she most likely isn't - the issue is she's siding with fascists because they share the same hateful rhetoric and is willing to defend and normalize their behavior because she sees them as allies and the "woke leftists" as the enemy.
Im dont know how twitter works and couldnt find the multiple times she denied that the salute was sincere, but the first one looked like a joke(because of the text)
The timing could also just be a coincidence
Edit: i missed the obvious text in the "multiple times" link. This still looks like a coincidence since there isnt anything in the post that would make someone believe it was supporting hitler other than the name and the date
Somehow I half expect to find out space X through some crazy means accidentally stumbled into time and interdimensional travel. He will bring in another dimensions hitler, argue it's a good guy... Trump will explain that this one's ok because in his dimension none of the people he killed were called jews, so he's ok, Hitler will meet with Nyetnyahu, the 2 will quickly become friends and the republicans will declare opposing alt-hitler as anti-semetic.
Well, she did previously recommend and endorse "political activists" (transphobes) who then turned out to be huge nazis, white supremacists, holocaust deniers, etc.
