These are terms that have been used against disabled people as a way to dehumanize and belittle them in the past. They were medical terms but as I said, they then became a way to belittle disabled people. This would be considered slurs. Today, they're considered everyday insults because they "changed" in meaning, the thing is, this "change in meaning" still connects to the original meaning. For example, idiot is used to describe someone who is untelligent, and this is also how it was used in the past. Instead of just creating a new word to do this, they choose a slur. If you like, I can give you evidence on why these are considered slurs.

without any medical connotation or targeting a specific group of people which is what a slur is.

And with this logic, this can be used for other types of slurs. Within time, they can "change meaning" as well. The thing is, people don't allow it to and that's what I find hypocritical about this. How can we be okay with xyz (which, not even using idiot, but I have seen people use autism and retard, which are slurs still and not called out for it. Just on here from time to time or another sub but on other websites and off the internet. Not only this but people using disabilities to describe something in negative connotation) but say "stop! You can't say that" to others. It's either all can be used or none can.

Either all slurs are okay or none are. Anything can be used as an insult or none can. If we are selective, we are also being just as language policing and hypocritical.
