I don't know much about Greta, except that many young people are starting to take activist roles-probably bc most of us that are older feel 'beat down' to stop many of the corrupt things in this world. I had to post this short video, mostly-for Dr. Tony's response where he laughs when ask, "What do you think about ASD as being called a mental illness." His laugh & response, that it's 'last century thinking.' I JUST LOVE HIM!
