But the fact is, discussions about the negative effect of a word such as “dumb” – a term originally denoting a deaf person who did not use speech, but which now functions as slang for something brutish, uninteresting or of low intelligence
dumb (adj.)
Old English dumb, of persons, "mute, silent, refraining from speaking or unable to speak," from Proto-Germanic *dumbaz "dumb, dull," which is perhaps from PIE *dheubh- "confusion, stupefaction, dizziness,"
Now, as for actual discussion to be had, unfortunately our language is entirely coded in slights towards different groups of people. In calling someone "a sinister villain who's a part of a cabal", I've called them a left (handed) farmer who is Jewish.
At some point we do need to accept that these negative words, which are at their fundamentals, slights to certain groups of people, have taken on a new meaning, and that their misuse as slights against those people only really applies contextually. I do think that terms like "stupid" and "idiot" have achieved that level of shift.
Feel free to disagree with me of course, I'm not here to tell you you or your experience is wrong, and I'm more than happy to have an actual discussion on this. ❤️
