You aren't understanding that no one wants people who think like you playing this game. If you are triggered by gay parent's any lgbt tag games aren't for you because you guessed it! People in the lgbt space will play them and they don't give a damn about what you are whining about just like we wouldn't give 2 shits about if the parent's were straight. But you don't see us demanding trigger warnings for straight parents in other books.
Go try find a hetero based christian game or some shit. Hopefully they have gender selection for you. Some mcs are gay too that's the whole point of a game where you can choose your gender and your ROs. Must be the gay dad's that inspired us.
