Natalie should know better. But also... the really nasty shit under Obama was heavily under-reported and only ever seemed to penetrate media in a select few circuits. Casually tossing off a "What even did Obama do that was so bad?" is almost forgivable if you're not a terminally online 30-year-old who makes hour long YouTube videos about politics, history, and culture.
I think she's joking about how people over-report his trivial shit. But it can be read as blithely ignoring the monstrous crimes Obama did commit while in office, because it echoes a lot of the liberal apologia of the administration that amounted to "The worst thing Obama ever did was wear a tan suit".
While I don't think she has talked about Obama's war crimes or things adjacent to it, I find it hard to believe that she would be saying that seriously especially the both sides part. Tho her response to the criticism doesn't make it better.
You're reading it wrong, she's stating you can't make a moral equivalence between Obama and, say, Trump or something because supposedly the worst things obama did were silly.
For me, it's someone that savvy casually dropping a "both sides" comment. If I didn't know better I'd assume it was bait. Its hard to imagine that level of cluelessness.
