i went to dallas and stopped by the jfk shooting museum. real neat. real somber. there's a yellow x on the asphalt where he was shot, and every few dozen minutes when there's a break in traffic there'd be a tiktok kid popping out there to get a cheery selfie or video. at first, I thought "they don't quite understand where they are, they're just dumb kids" and then the constant stream (i promise i got it by the third one) of them made me realize they were all ragebating us olds.

You are certainly correct about that, but you and OP haven't answered my question. I really wonder if OP was saying that they wouldn't be upset, even if they had a personal connection to that specific memorial.

My guess with OP's comment was more like they didn't see how it affects them, versus any other answer. I believe society won't move forward as long as everyone only ever sees the world through the lens of "how does this affect me". But this is all just me guessing.
