"OTOH, when I sit back and contemplate, it becomes easy to see why an adult autistic male can come to sincerely adore a young female. He's finally found someone whose logic he can understand on a base level, and totally agree with, without any intended hidden usurper motive at all."
I have to admit, this is one of the things I like about young girls.
Few hidden motives, what you see is mostly what you get. If she likes you, she'll let you know. If she DOESN'T like you, she'll let you know that, too. No guessing games, no shit tests.
I mean, little girls can still be devious, especially about things like staying up past their bedtime or getting an extra cookie, but on the important things they don't play around.
