Censorship is censorship, regardless of who it is that's is the censor.
What is censored and why is more important.
Well ...
I believe this game is for 18+ ... so no responsible parent should allow his child to be anywehere near. O_o
It sounds kinda funny to me ... like demanding parental control being aplied to hardcore fetish porn movie.

And I not terribly fond of that rating in BG game, or at least how it is utilized. I don't know how BG would be rated, but I played BG1&2 as a young teenager, and frankly it didn't scontain anything terribly unipropriate. IMO BG3 could very easily not be 18+ and be better for it.
The problem I would point out in that reasoning is that "hardcore fetish port movie" is meant to be a hardcore fetish porn movie. Take that away and you are left with nothing. One would hope that there is far more to BG3 then janky digital sex scenes, profanities and bloodsplatters.
