I saw the ableism of Avatar with Jake Sully right away, but as for Geordi La Forge...I don't really see it. Next Gen takes place in the 24th century, of course we'd have new kinds of assistive technology. (Though it irks the shit out of me that they never developed lightweight antigrav wheelchairs as opposed to the awful things TOS and TNG had instead.) Part of science fiction is new technology, including that of the adaptive kind. (Though in my SF futures, there's more of a societal change too and accessibility isn't just here-have-some-tech.)

If I were gonna bitch about ableism in Trek, I'd bitch about the wheelchair thing, and about Julian Bashir's parents. So he was born with cognitive disabilities. It's no one's fault, it's the way things fukken are, he's not a defective "thing" to be "fixed."
