And I thought you were being autistic before, holy fuck. You're not even being high-functioning about it. Most of those names belong to family members, who would want their names to appear similar simply for that reason. Also, a lot of those characters are from LoK, which is fanfiction-tier. Of course they'd make names sound alike. But even if none of that mattered, you're still not gonna convince anyone that a fucking genderbent cartoon needs a "g" in her fucking fan-name.
Props to you for doing research, though.
