He's taking a jab at the Olivia Hill rule:Heh, you mean like the token "are you 18?" that basically every game featured on this site have, which I guarantee is not the case for every player of said games.
If you're a fascist, you're not welcome to play this game. It's against the rules. If you're reading this and thinking, "You just call everyone you disagree with a fascist," then you're probably a fascist, or incapable of drawing inferences from context and acknowledging a dangerous political climate that causes the oppressed to be hyperbolic. Don't play this game. Heal yourself. Grow. Learn. Watch some Mr. Rogers' Neighborhood or something.
