As this article points out in the introduction, this is antithetical to Jewish liturgy. Moses himself had a speech impediment, and needed Aaron's assistance to take his prophetic message to the Pharaoh, as well as to the Jewish people. If anything, this is a model of inclusion at work: Moses was provided with the necessary accommodations which allowed his leadership to shine.
As a counselor at the Jewish summer camp Camp Ramah, the author of the article discovered that sharing each camper's challenges was empowering for all, as both typical and disabled campers realized that we are not defined or limited by our challenges. This echoes the insight that the mom in yesterday's post made when talking with her children. We all have our unique strengths and challenges. Society arbitrarily labels some of these "disabilities", but these are artificial constructs, not facts of reality. The reality, which we aspire to see reflected in society, is that our value is in our common humanity and in the way we treat each other.
