If it helps clarify things for you, the person you are arguing with doesn’t understand what you are trying to say with regards to how autism informs your interactions with others online and is arguing against a point you aren’t trying to make. They are however entirely too dug into arguing against that point to easily and effectively get them to understand what you are actually saying and respond to that without the baggage of already deciding that they entirely disagree with you to the point they think they are entitled to be rude to you because you don’t agree with them.

The conversation you are in in this thread is more difficult than it ought to be and while some element of that may be due to your autism, there’s also a lot of failures from the other side of it making the conversation harder than it should be. At this point you are not being treated kindly and respectfully by the other person (because they are frustrated and handling it poorly.) Better to just disengage with them and shrug it off as a misunderstanding and bad behaviour not of your making as best as you are able to do so.
