It depends upon the person. This is a topic of discussion that pops up from time to time,..."How can I get someone to understand?" In many cases, you cannot. There are a handful of reasons for this including, but not limited to: (1) Some neurotypicals lack the same empathy that some autistics do,...specifically, the type of empathy that allows them to take another's perspective. This has been my experience, even with my healthcare co-workers. Although they seemed accepting of my diagnosis, their typical response was no response, at all. Keep in mind, these are the same people that work with me in a huge children's hospital and deal with autistic children from time to time,...if anyone was going to be empathetic,...this group would be,...but no. (2) Some people you know have already made a "moral diagnosis" of you, may actually be unwilling to entertain your perspective or diagnosis,...and anything you say in terms of a "diagnosis" is simply going to be a interpreted as you "making up excuses", totally denying "a label", or will actively try to minimize your symptoms because "they have them too". I certainly have those people in my life,...well, not so much any more,...as I've cut many of those ties.
There are people who are genuinely interested in autism and wish to learn more about it,...not many, but they are out there,...in which case, there are several autism support websites, YouTube videos, and thousands of scientific journal articles.
For the most part, I would have to say, that we do have some control over the people we keep company with. One of the advantages of my autism, is that I am one that has a posterior pituitary issue that results in low levels of oxytocin and vasopressin,...the "love hormones",...the hormones that allow for interpersonal bonding. So for me, I generally have a very low threshold for negative people in my life,...I just simply stop interacting with them, and can do it with very little regret, emotional conflict, or thought.
