Yeah, so Kylo Ren isn't evil because he tried to blow up a planet or kill his dad or anything. No he's evil cause he was white.
As for the second image:
1. Rey living alone in no way indicates she's autistic. Maybe she just likes to be alone.
2. She scavenges stuff not because they're "interesting and probably costing her food", she takes what she scavenges and uses it to buy food. The only significant object we see is her staff, which is probably just defensive, and a pilots mask which (although it was probably in the movie to indicate she want to leave like Luke) may just be something she likes.
3. The guy who short changes her seems like she's dealt with him before, and also has a lot of goons, so it's quite possible she doesn't want to get on his bad side. They're also completely ignoring that when she gives him some of her salvage he gives her an amount, and she tells him that IIRC, "Last week that was worth two portions." So she did verbally confront him when he tried to give her a lower price than she expected.
4. This whole "holding hands" bs is referring to when Order Troops showed up and Finn grabbed her by the hand and started to run. It's nothing to do with "she's autistic and doesn't like to be touched", it's just that someone she never met grabbed her and started running!
5. While it does seem like a lot of people disregard droids, Luke had a fondness for R2D2, specifically in a New Hope where someone offered to give him a new droid and he refuses. Also a lot of droids have very clear personalities, so it would make sense people could emphasize with them, especially one as cutesy as BB-8.
6. How is that autistic? The only clue regarding her parents fate is that they were taken away from her as a child, and it's apparently a symptom of autism that she waited for them? Especially considering in the Star Wars universe, you're not just searching throughout the Earth to find someone, you're searching thousands of planets. I mean, the plot of the movie is about people trying to find Luke. It would make most sense to just wait for them on Jakku.
Apparently waiting on a planet while desperately hoping your parents might one day return to you is autistic.
