The more I thought about his life, the more I realized that the reasons for most of his issues stem less from disability and more from dysfunction.
His parents left him with a shit babysitter that stunted his development so they could go drinking, Bob let him legally change his name when he was nine because a robot bear misheard him, Bob moved districts because he didn't want to put Chris in classes that could've helped him, Bob paid girls to hang out with Chris so he wouldn't be lonely, neither Bob or Barb had any expectations for him and just let him waste his life drawing Sonichu and getting into run-ins with mall security guards, Bob straight up encouraged him to get on welfare and not look for a job.
Another thing is that Chris was isolated as fuck by the time the trolling kicked into full swing, and while some of it was his own fault (IE. Megan, The Game Place), a lot of it wasn't on him. He lost contact with everyone after high school (probably because the majority of his "friends" were paid actresses) and all he would do is sit in his room all alone with his only form of interaction being his senile parents who were isolated as fuck themselves. Both Bob and Barb were cut off from the majority of the extended family long before Chris was discovered and I can't recall anything on the CWCki mentioning if Bob or Barb had any close acquaintances. If you look at videos of Chris over the years, you can see his verbal skills noticeably worsen as the years go by (compare the high school report video to the Green Country conspiracy video and then compare that one to a modern Chris video) and I completely believe it's because he barely had anyone to regularly interact with except for two out of touch old farts, and it got infinitely worse when he got discovered by the internet, which his parents also didn't do shit about.
Even if Chris wasn't born with autism, he would've ended up a complete mess of a human being regardless because being raised by Bob and Barb would've fucked up even the most well-adjusted kids. The autism was just gravy.
