@Laurelai @tbeckett Eek. No, it is definitely not. :/
That's not what you were talking about anyway. You were complaining about people correcting spelling errors. Please see my previous comments regarding that.
If you are concerned about classism and ablism, I suggest supporting efforts to aid folks affected by those problems -- better education, health care, and legal protections. People correcting spelling errors is not a problem of any sort.
