Yeah it’s not a mastodon issue any more than racist speech is an issue with our ability to vocalize as humans.
Similarly, the solution to people saying racist things isn’t for all speech to be policed by a central authority, it’s for societies themselves to learn to identify and reject racism.
I remember knowing that knives will cut you and make you bleed, and that when people were shot in movies they would bleed, therefore bullets must be shaped like little blades.
