But they're not literal children. They are IMAGINARY CHARACTERS FROM A CARTOON, MEANT TO ENTERTAIN PEOPLE. If these characters were actual living humans of the same age as they are in the show, then you would see many people calling out the dev and reporting their game out of actual concern. Because unlike you, those that do enjoy this game can separate Fiction from Reality. And saying that people have mental issues from doing so sounds ableist as hell and makes you look like a bigger clown than you already were.
Also, the reason I brought up your preferences is because there are people who could look at what you enjoy and say that you are just as bad and possibly even worse than those who play this game. You came in here trying to harass and bully people who didn't know who you were at all over a preference that you don't have. You're just wanting to be morally superior and jerk off to that feeling of "I am better than anyone in this comment section," like a terminally online Twitter white knight who believes they are the only one in the right of everything. And from what I've seen, those that virtue signal the most about imaginary characters usually have some pretty fucked up skeletons in their closets. So unless you want people to believe the actual worst about you, You should just leave the comments of this game alone and just move on. Only one wanting to start shit here is you, the rest of the people just want to go on with their lives. Just blacklist the dev of this game and any other game that bothers you and ignore them.
