How did society go so crazy that this even became a seriously discussed question? How did we let concepts like "inclusiveness" and "ableism" grow to the point that people could think that curing disabilities is a bad thing?
Not one of the people preaching about "ableism" are giving themselves disabilities because they're oh so wonderful and that tells you really all you need to know that nonsense. Disabilities suck, take it from me, and no, it is not remotely wrong to cure them.
