I'm autistic too, and have 39 years of communication problems behind me.
From my experience, I'd say that there is no way communication will improve if one of the sides refuses to make an effort (or worse, try to delete people who mean no harm).
It can be extremely difficult as an autistic person to socialize, because we feel we are constantly doing an effort, and the other ones don't.
But we have to remember that before we tell them that a problem exists, they CAN'T make an effort, even if they are very nice and considerate. And that we cannot ask people for effort if we don't make an effort ourselves. We cannot make considerate people suffer for what inconsiderate people did to us, or for the fact we will always been the ones making more efforts, because the majority of the people we meet don't even know about our issues.
Telling someone simply "No, I won't read it" is rude for the majority of people (even part of the autistic ones). Explaining why makes things less rude, and also give extremely valuable information to the person who asked the question.
No one will by default think it is respectful to just say 'no', and disrespectful to explain why. So, I get that you don't like it, but understand people did it out of respect and not the contrary. If you are not ready to accept that others show you respect in a different way, you cannot possibly expect them to accept you and adapt their behavior to make you more comfortable.
