There’s a difference between regretting a post and taking your ball to go home.

If so, it's entirely possible to edit the post by crossing out or even erasing all the offensive words and adding or substituting an apology. "I've realized I posted something rude and insensitive here, so I've deleted it and will try to do better in the future."

not just 'whoop, someone made the same joke as me, welp, here I sit'

yes i often do it because it sounds wierd or it is could be a misinterpretation. usually people are aggressive with things like misinformaiton/propaganda usually leave it up. aside from teh bots who delete theirs immediately.
