You're the one that is sexualizing that image. I looked at it, and said to myself "I dunno what game this is but she looks like a cute maid".

At no point did I even think that is a child. Children don't have massive tits and wide hips, that's an adult female's body type.

I'm sure you'd find the anime style depictions of 70 year old historical warships in Azur Lane somehow creepy too.

Put it into perspective, considering the reply you're responding to, particularly mine.

Prior to your edit, you mentioned "these types" of people (people into anime) would sexualize your niece. Noone said anything about sexualizing real people. A lot of people who are into anime don't even like real people. "3d pig disgusting" is a real sentiment in a lot of the anime world. It definitely comes off as a thought you have had towards your niece, and that is the creepy part. The fact that you edited it out only reinforces that further.
