I wouldn’t call it “understanding” if you assume a meaning to a word that doesn’t have that meaning.
It’s funny in the same way as native Americans saying “ugh”. If you’re ignorant, you laugh. If you aren’t, you facepalm. A joke that just makes its teller look like an ignorant idiot who is happy to trample other cultures is not a joke that should me made.
It is any better.
It’s also not okay what DC did, but the transgressions are very different in scale.
Kimmel was faired for saying “MAGA is trying to make it look like the shooter wasn’t a MAGA activist”, while Felker-Martin got fired for saying “it’s a good thing Kirk can no longer take part in podcasts.”
I don’t think either of those is grounds for firing, but it’s not good to bring them to the same level.
