... and it was just a cheap dunk on Musk. I actually quite like Elon overall, although my shock in that comment is genuine, but since liberals decided he's a traitor to the cause mindless anti-musketry is in vogue.
Normally I post things that go against the zeitgeist, but in that case we happened to align = instant karma.
Whereas, for example, a drastically higher effort comment with five citations showing something unexpected about climatology (e.g. that Arctic sea ice is at the same level right now as it was in 1981) will get +3 at most, possibly -1, quite possibly flagged. Often hard to tell what will happen. I sometimes suspect the absolute number of upvotes is much larger but that they get balanced with a nearly equal number of downvotes.
