sheldon from Big Bang Theory is a clown for autism. a clown meaning a character with a specific emotion/behaviour, in this case severe autistic traits, taken to an (un)comfortable extreme to teach people "not to be like that because its too much, here's what happens if you are that extreme"
so parents going "haha look sheldon is just like you" means you are equal an extreme caricature and uncomfort causing to others :(
