This reminds me of the early days of Trump, when he'd be saying things, and mainstream sources were like "Wow, he's just spewing absolute nonsense" and not realising that Trump, and now Musk, is just reflecting back a collective shared insanity to an audience who has been actively building this alternate world for a long time.

"cis is a slur" isn't a spur of the moment bit of stupidity, it's a long running bit of stupidity that is shared by a large audience that ranges from active and knowing evil to unhinged conspiracy believers and all the various shades of Trumpism in between.
