As a disabled person, I face ableism and ableist language every day. Some people use ableist language without even knowing that it is ableist. I thought it would be good for folks to take a look at the attached BBC article and expand their perspectives a bit.
It takes people time to change their minds. Hopefully you run across this debate in different contexts. In fact, try bringing it up with friends and/or family to see how they react!
