This is a fair analysis, but also consider: I don’t think this celebration ever thought that much about the political implications. It started as a meme of a knife in a bottle of Caesar dressing. I know that’s probably frustrating for historians and classical literature fans, and maybe we should take it a bit more seriously.
That being said, you are possibly the first person to think that deeply about Tumblr’s view of this holiday. You made some claims about how Tumblr users view the historic event, and maybe it’s just because we’re in different circles, but I don’t usually see much thought. No one really talks about what Caesar conquered or how Brutus and the senate handled the aftermath, and no one really picks sides.
It’s more “beware the ides,” Caesar should’ve listened to his wife and stayed home, he ran into my knife 23 times even though there were supposed to be 60, “et tu Bruté,” Pizza Pizza with dressing and a side of salad.
The closest I’ve seen it get to serious is “Hey, any current senators want to be hilarious?” Which, fair, in that regard we maybe should think more about what the aftermath was and what a coup like that today would mean.
But also that gets drowned out in puns, edits of classic art, Mean Girls gifs, eyes of Marge, and the occasional acknowledgement of it also being a bad day across fictional history with Mr. Crocker losing his happiness, Marty McFly’s dad dying in the bad timeline, and even more if you get into some if the less universal fandoms (seriously, a few years ago I did a post trying to list them all, and I feel like every year a new one gets added).
Anyway, this was way too long of a comment where I said a whole lot of nothing, but also, that’s kinda what the Ides of March is: a lot of hype with little to no thought at all.
