i forgot how safe and sheltered our group is here.
I know what you mean.
There's nothing like the internet to make people feel like they are qualified to give expert advice on things about which they have no clue. One of my favorite lines from a movie ("Snow Cake") is, "I know all about autism. I saw that film."
I suppose it's not too hard to weed out the people who are just talking out their, er, ear. If I find someone's blog, and they are a mother of 3, and have a couple of kids on the spectrum, then I'm going to take what they say more seriously than some 20 year old whose neighbor has a nephew "wid a$$ burgers". Still, it hurts when people say ignorant things.
