I'm of NI descent with immediate family who live and work in cities in England. They've all retained their NI accent and don't face any of the issues outlined by the OP. They're all NT.
I'm autistic and I don't experience what the OP does which may be due to a few reasons. I'm female and have trained myself to communicate as and when necessary. I'm happy enough in my own skin not to care what others think of me. I don't have any social media presence apart from this forum. I have a cynical view of Facebook and can see it for what it is - fake and potentially damaging. I have friends and am able to socialise within my own limitations therefore I don't have a need for new friends. I work in a professional environment with policies in place to tackle racism (and other prejudices). I'm older than the OP.
I have never witnessed prejudice towards people from NI and I know a lot of people from NI as we have big, extended families.
