Your post reads extremely arrogantly. It's a "I am very smart" type of communication style.
None of the points you bring up are specific to autistic individuals. I'm allistic (as you put it) and, realistically, not that intelligent, but I experience the first two of your points on a regular basis. But I've learned to modify my handling of these types of situations so that, most of the time, I get a positive/productive response.
Now I obviously can't know how you communicate outside your blog posts. But it may be prudent to think about it – if you come across as arrogant or a "know it all", then the "you don't acknowledge when you're wrong" is just a nicer way of saying it.
And when people get a “vibe” of arrogance/know-it-all-ness from a person, they will be much less willing to accept, well, anything. And for good reason. This especially applies to corrections, "let's play 20 questions" and long-winded explanations of context (especially if you explain something they already know, even partially).
