Why are there people disrespecting Autistic people?

I know....people are so ignorant these days, and it breaks my heart...I have a younger brother who is autistic, and I know quite a few other kids who are too...and they really are just like anyone else...they just appear to be different because they dont communicate/learn the same way as us....but its so sad. I wish that people would have a hear and learn to accept each other for who we are, and realize we are all brothers and sisters of God, who just want one thing...to be loved, no matter what.
