I just have this nagging feeling it was not just a fantasy. Cuddling with mummy in her bed as an adult son is called uncosumated incest. Fantasies are desires which are not or cannot come true, usually, but I bet you people would say yes to most of their fantasies.On one side I want to believe Chris truly doesnt know the implications of what he is doing and he is saying thats okay because it goes along with his narrative...
Then I remember this is a guy that admitted that he doesnt find incest and sexual fantasies with your fucking mother to be wrong.
He grew up as a girly wuss who's afraid of men and never identified with the masculine bully characters which dominated his cartoons. He spent all his time around boring teenaged girls and never participated in any real masculine activity with other boys. Most of the people "responsible" for his misfortune have been either male trolls or just IRL men who had the audacity to fuck the women he was in love with. Or ban him from their stores. Or arrest him. He legitimately hates all men who aren't paternal figures giving him stuff (Bob, Santa Clause, Optimus Prime, Sonic). He's uncomfortable with being a man, because he likes girly stuff and pretty dolls. Literally Current Year says you can just be a girl if you want to, so Chris did that.
Only way to know for sure would be to have access to Chris' mind, so we can only speculate. We do know that he had gender identity issues before the trolling though.
