See - I don't get this. I've heard people mention it about the deaf community, but it just doesn't make sense to me - perhaps I'm missing something.
I have congenital hearing loss in both ears, and wear hearing aids. I don't know ASL (at least not well enough to use), as I am more or less able to function with hearing aids, with the usual caveats - background noise, group settings, still quite reliant on lip-reading and context to fill in gaps etc.
Within my financial means, I would glad pay to wave a magic wand and restore my ears to "normal". This gene therapy sounds interesting, but I'm not sure if that mutation is the cause of my hearing loss. And I'm always wary of side-effects, haha.
I do see my hearing loss as a disability - and no matter how much you try to dress it up, or with "don't diss my dis-ability" PR campaigns - it still does suck every day. I'm not saying you should discriminate against people for their disability - and I've steadfastly advocated for increased accessibility to level the playing field (e.g. in my workplace, at church, in the community). But I'm not exactly Matt Murdoch or Echo here.
And yes, I'm also "neuro-diverse" (starts with A) - and yes, I guess you could argue there's advantages there, under specific circumstances. But there's most definitely a penalty there.
