OP why are you equating autism and IQ?
I'm autistic. I have a high IQ.
My use of written English is excellent.
I try very hard not to be blunt or rude. Always.
You are doing autistic people a great disservice, starting all these threads about your work woes, and trying to blame your difficulties on your autism.
Try to accept help, and try not to assume that everyone is your enemy.
Learn how to write better, clear English. And thank people who are offering help.
