No. Ableism (not sure why the quotes, comes off as a little sarcastic) is expecting and demeaning individuals--either purposefully or implicitly due to environmental design--for not achieving some arbitrary standard of “normal”. No one advocating for better treatment of people is suggesting a Bergeron-esque reality where those who are performing must be handicapped for equality. It is more about making social systems and attitudes welcoming for those who were traditionally seen as worthless (especially in a system that valued productive work above the health of the individual). Making room for others doesn't mean dragging others down, you know?
