What are you more likely to remember a week from now: Meatpistol or Metapistol? Reminds me of the resistor color code mnemonic, something I memorized for life the first time I heard it.
The original comment was flagged to oblivion, but I'm assuming it quoted one of the ones on https://en.wikipedia.org/wiki/List_of_electronic_color_code_..., in which case - unless you feel inclined to start yet another Wikipedia edit war - it will probably not "be forgotten with the rest of the mental trash".
I too hope that nobody actually uses such a mnemonic in this day and age, but for such a mnemonic to be forgotten entirely would be a massive loss. Whitewashing the past of its blatant racism and sexism will only serve to erase the reminders we as a society have of why the present is an improvement on the past. Every artifact of such archaic and abhorrent beliefs serves as yet another datapoint demonstrating the whole concept of "Mak[ing] America Great Again™" to be misguided at best and abhorrent at worst.
In other words: we absolutely shouldn't be teaching such a mnemonic in classrooms, but we absolutely should continue to document their existence as evidence of exactly how fucked up the past really was.
