I think it's a super complicated topic. My understanding of the quote is that ableism is much bigger and more complicated than language, but we should be aware of how our language reflects ableist views - like the normalization of ableist slurs into our everyday vernacular, for example. In other words, our society is so comfortable with ableism, that even disabled people and advocates for disability rights may use ableist terminology regularly, whether or not they're aware of the origins.

I, personally, don't believe that "lame" is necessarily a word that needs to be changed, but I do believe it's a word with ableist origins. Like our conversation on "dumb", IMO most people don't think about the technical definition of "lame" anymore - but I might be wrong, or it might be regional. It's ultimately a personal choice whether or not it feels hurtful - and obviously, if someone tells you to not use a term around them, that's important to respect.

The key takeaway, to me, is that we should be mindful of how much ableism is normalized in our lives. I think you're definitely doing that, based on this post. It doesn't mean that using terms on this list is only ableist if you're thinking negatively about disabled people when you use it; it means that we should be thoughtful with our language, but more importantly, thoughtful of how our words and actions may be reinforcing hurtful systems. To use the example from before - if someone doesn't use the word "crazy" except when describing mentally ill people, that can speak to how they see mentally ill people as not just people who are ill, but as people who are undesirable boogeymen.

Take it on a case-by-case basis, IMO, and follow your gut if you feel shitty about certain words - better safe than sorry. But, at the end of the day, it's just... complicated!

Hm... I'd actually disagree with that conclusion? I think what the author is saying there is that ableism isn't simply a matter of the words being used. A statement that treats disabled people as subhuman isn't okay because it avoids using these words - it's still ableist.

From the beginning of the article (emphasis mine):

Note that only some of the words on this page are actually slurs. Many of the words and phrases on this page are not generally considered slurs, and in fact, may not actually be hurtful, upsetting, retraumatizing, or offensive to many disabled people. They are simply considered ableist (the way that referring to a woman as emotionally fragile is sexist, but not a slur).

Not everyone has the ability to be mindful of how certain language originated in ableism and this reinforces it. But for those of us who can, it's a good idea to try.
