That ditch is getting deeper with each post.
You don't need direct experience of ableism to be able to judge what it is and apply an objective test to a post to see if it meets the required threshold
Ableism takes many forms and, like other flavours of bigotry, can be insidious and sly.
A non-disabled person cannot have the knowledge and experience to always recognise when ableism is happening. Just like I, as a white person, cannot have the knowledge and experience to always recognise when racism is happening.
I would not dare to have the audacity to talk to people of colour about what defines racism in the way that you are talking to disabled people on this thread about what defines ableism. That you do is telling in itself.
