i'm also not talking taking it into RP where the themes are not already present. i'm talking "an admin writes a setting where women are not allowed to do xyz" and you write a character that agrees with that in a non-violent manner-- and you get OOC backlash for it from people who, if they want to be free of those themes, could easily have read "this setting has misogyny" and not joined.
it's like being yelled at for playing a murderer in a crime RP.
hell, even non-RL opinions that aren't "strictly correct" from the ooc perspective of the site can get you harassed, such as playing someone who supports the Empire in a Star Wars RP (unless they are a sexy white guy).
I understand there's nuance in the situation, and sometimes people do go overboard, but I like when characters have flaws that reflect a setting and limited view of the setting, i guess. A perfect example is, when Sylvanas was doing her thing during BFA, it was expected that your character knew everything exactly as it happened. I respected the players who played with propaganda and limited worldviews in play over those that immediately knew everything Sylvanas was up to and everything Sylvanas did, but you couldn't actually RP them with everyone because odds are you'd run into someone whose OOC and IC opinions were perfectly lined up, and they'd "lore police" you IC for it.
my final edit, i swear: i also had a member afraid to app rose quartz from steven universe on my site because Rose is a character that is definitively flawed within the narrative and is constrained by a myriad of factors outside her control and some within. So it definitely isn't just "well some ppl don't wanna RP with Racism," it's just that some people don't wanna deal with characters that aren't perfect representations of their personal takes on a piece of media, and it's exhausting.
So I really respect when players are willing to not only RP as characters they don't agree with, but *with* characters they don't personally agree with. It's a good sign for me.
