Yeah, people made the same arguments about 'gay' and 'fag'.

Retarded was the word of choice medically in the 60's - 80's for people with developmental disabilities. It derives from the Latin word Tardus which means slow or late.

Languages evolve, but the euphemistic treadmill is ongoing. The word 'cretin' derived from the word 'Christian', the person who coined it intended it to mean that people with cognitive impairments were still people worthy of respect. And now it's just a straight up insult. Similar with 'idiot' and 'moron'.

And these days you can look at wojaks which use physical differences like drooling or missing half a head or being physically unattractive in unconventional ways to indicate ignorance or stupidity.

Every word that people use to try to describe people with disabilities respectfully becomes a slur. That's because of ableism. It's just not talked about much.

I'm 39 and saying calling things "gay" and "retarded" was just what we did when we were growing up. We didn't really mean you were homosexual or mentally disabled. It was just the times. I'm fairly liberal, but old habits really do die hard.

Same, even now I've been making an effort not to for years, it still sometimes pops up in my internal monologue. Over-writing preprogrammed habits is hard, I am right there with you.

Lame is kind of an old word for someone or something with a bad leg or legs.

Like how a horse is lame if its leg is broken.

You can pry “lame” and “spaz” outta my cold, dead tongue!

Technically yes but I'm disabled and it's literally never seemed ableist to me. I've never heard anyone use it as anything other than "that's a bummer" or "you're ruining the vibe"

I think that specific word has been reformed

You can do as you wish, but I prefer not to join. I don't think it's fair to people with spasticity symptoms, an often very painful condition, to be associated with someone who is just a greedy selfish arrogant waste of skin. They suffer enough without being insulted too.

I think it's partly a symptom of our world being super-connected. There are some loud people out there with some really poorly founded ideas, and opinions which most people would consider absurd. Previously that might be only one or two people in a community, but the internet has changed that for good.

I also try not to do it anymore to help people with disabilities which prevent them from readily picking up on sarcasm like autism. I don't need to accidentally influence someone who has taken me at face value. It's so hard not to revert back to old habits though.
