dude, i sympathise but i have to disagree with you quite heavily on part of your argument.
MARE DOESN'T LOOK 10-12, HE LOOKS LIKE HALF THE ADULT FEMBOYS ON TWITCH. even if you wanted to make an argument about their appearance, YOU ACKNOWLEDGED THEY WERE AN ADULT. you claiming they are "child like" can also be used to justify THEIR arguments, as they can claim that the idf people "look too young", so don't open that avenue for argument.
i personally dont care if someone likes the "900 year old loli" or if they like rise from persona, my standard is so long as they dont like real kids or animals. i prefer characters "blessed in the chest" but i have played plenty of eroge that also includes such characters themselves. its why i cant stand this type of argument as several games you have commented on also have characters that someone could claim "looks young".
TL:DR, just point out the evidence provided is false cause right now your doing the same false pdf accusations he is. i understand why you are doing it, but it sets yourself up for further trolling by his accounts
