People are free and welcome to criticise the game, they just need to back it up. The most common problem is the number of people who come here and say “I’ve played dozens of better games” then when challenged to name one, can’t or won‘t.
Those who do name better games, when debated can’t or don’t really back up their opinions. They come with the attitude ‘game x is better, because it has better art, or better mechanics or a better plot or better characterisation’. When someone here challenges that they don’t like it. They don’t want a discussion. When people on this thread point out BADIK might not be as good on a individual aspect such, but with all aspects combined it’s better, people won’t accept it.
As for the people who don’t like criticism of their favourite characters, I agree this can seem quite juvenile. Over all I think this is done in good fun, but there are one or two who take things a bit personally.But remember this is the internet, the place people will try to convince you that if a character they like has sex with anyone but the MC they are being made a cuck because of self insertion.
