my son has Autism, he is not rude

Like every typical child his age, Andrew has behavioral issues: he does not follow request, has little tantrums, tells you inappropriate things. The fact that he has Autism makes these behaviors more pronounced. Recently, some people made the hurtful comment that my son is rude and that he needs harsh discipline. I have learned not to judge others too quickly based on a quick observation; I wish more people would too.
