In my experience, if there's someone with his/her mind made up, and they don't want to learn anything, you're wasting your time and you need those people out of your life ASAP. There are SO MANY people out there, who think that any deviation from THEIR way of thinking, and from THEIR ideals, is a defect and some kind of terrible skeleton to keep in a closet. My wife has a 2-year-old cousin, who we are fairly sure has either AS or a form of autism. His parents are spending all their time (and their family's money) on all kinds of counseling and meds, thinking they're going to "FIX" the kid. FORCING him to make eye contact, forcing him to hug and to allow hugging, when he screams in anguish from those forms of attention. Very frustrating for me, and and for my wife (a former special ed teacher) to watch happening. It's kind of like seeing a (definitely) Gay child born into a Mormon household. Sadly, the very BEST that can be hoped for there, is a life of denial and anger, with the worst being a teen suicide. Seen it happen!
Closed-mind people are the true mentally disabled, and the most damning force on people with differences who want to learn and grow, on this earth.
