I saw that tweet and thought it looked crazy. To me, it sounds like a death threat. Especially given that it's posted on X.com, after a really heated argument, with no clarification afterwards.
If you didn't actually post that tweet, that's great! I'm happy to be corrected
If you hear a rumor that sounds too crazy to be true on social media, maybe don't repeat it as fact. Imagine how you would feel reading something like that.
