Child-like characters?

[Nestama]

I say it is fair enough to say that at least Ryne example is a bit hypocritical. You are completely right regarding SE being unable to control players presenting their characters in a sexual manner, so it is more problem that it is worth.

Fair point, however if you forget Ryne for a moment and instead focus on our character and what they have gone through...
Kidnapping (put to sleep, captured and then offered to Ifrit), framed for "murder," witnessing someone protecting us die before our eyes, drugged, almost killed (multiple times, but the most notable to me is the fight against Elidibus-Zenos), witnessing body horror and then finally almost becoming the thing we've been killing.

That's probably what SE was referring to. It's all a bit much for a kid.
