Insinuating disrespect to my son through Facebook?

[penpoint]

A rude family member is talking about mentally disabled people on facebook, and making a joke out if it. She knows that my son is autistic. This is what she puts up on facebook:

What should I do? Should I post something else on facebook about her (if so what?)
I know that two wrongs don't make a right. But I keep making rights (by being nice to them) but they keep stepping on me.

Two wrongs don't make a right.

Its just facebook. I post about politics, religion, sex, race, and yes, even retardation. Facebook is for everyones personal enjoyment. Whatever that individual person finds funny. If someone posts a pic on my fb of a child and i think its an ugly child, im likely to post something on my wall about ugly kids. It is what it is. Let it go.

Ignore it. You are better than they are. Drop all contact with them.

[Common Sense]

You are over reacting. This person is talking about a MOVIE.

just block them, and let facebook knows shes doing that, maybe if youre lucky they'll close her acct

I would just block that person and block them from my son's page too if he has one.

She probably isn't even thinking about you and your son. He isn't the centre of her universe the way he's yours. Ignore it.
