Yeah I just went ahead and blocked the troll. I would happily read and debate an actual opinion with (properly researched!) evidence, but this is someone who just wants to start shit, and I've got better things to do than argue with people like that.
Back to the subject at hand (or something related), over recent days I've noticed a current event that keeps popping up in my feeds (for reasons I honestly can't comprehend or explain, as I knew nothing of this beforehand), and I've realized that it's very much in the same vein as this topic:

This is Uzaki Hana, the title character of "Uzaki-chan Wants to Hang Out!" that has recently been getting an animated adaptation. It's a Slice of Life comedy about the spunky and slightly-ditzy heroine trying to get her (totally not) boyfriend to open up a little. Hana is 19 years old (it's stated as such in the first scene she appears in), and just happens to be really short (150cm) with a sizable bust (apparently it runs in the family). She actually acts like a typical anime teenager her age instead of like the child she appears to be (chest size notwithstanding), and gets fun poked at her for looking so young, but other characters quickly realize she's an adult and treat her as such. It's almost as if the manga exists to prove the point we've been discussing in this thread: that "young-looking =/= actually young".
...Try telling Twitter that.
As if to stomp on any hopes of acceptance and diversity I was hoping the common man had, apparently Western people who know of this character without actually knowing the character went batshit nuclear against her because she "looks like a child". There are way too many comments that use Hana as a means to accuse Japan of sexualizing a child. I've even seen a couple arts of Hana getting murdered to represent this hate that I wish I could unsee. It's bad enough that a significant part of Japan's own fanbase noticed and is vocally disturbed by the West's reaction.
I've seen real-life adults in my part of Canada who look younger than this - hell, one of them was one of my high school teachers who was 25-30 years old, and everyone treated her like a teacher despite looking like she could be a student! But apparently the majority of Western people aren't that kind. It puts into perspective that what @Archetype-Luna said about "Paranoia of Western Cancel Culture" might be more true than we might think, and it would certainly explain why SEGA would modify PSO2NA's height slider - I still think it's bloody stupid and spineless, but knowing the scope of the reaction they'd get, I can at least understand the choice now.
