I don't know you or yours but...
The retard comment is out of line (IMHO)
Being the step father of a special needs child (since the father had a similar opinion to the retard coment), I can tell you from personal experience that the kids involved in the Special Olympics get way more out of the competition than you, me, or most any of us ever will get in any competetive event.
Would their lives be better if they could eliminate, treat, or in any way resolve the conditions they suffer from.... HELL YES. But until then, helping them learn to deal with, and overcome, what ails them is more important than mocking them, or putting them down for their disabilities.
"Let me win. But if I cannot win, let me be brave in the attempt."
Sorry about that, but I'm getting thin skinned about it in the last few years.
