Whether you are the only one or you are not the only one is irrelevant. People have a right to have an opinion about what should or should not be important. This includes the games or the level we are talking about. If that bothers you, report such comments to the moderator and if they find it out of line they will deal with the issue. But to suggest that people cannot share their opinions is not only unrealistic but it is not going to happen. In my opinion people on the internet take a lot of things that are trivial too seriously. We are mostly talking about something that many people couldn't care less about. And if everyone cared enough they would not hide behind little funny names to express their opinions.
This is kind of like the woman that had the 8 children recently. When you put yourself out their or your opinions, people have the right to respond to those opinions. If that is something a person cannot handle, they need not every say anything on this or any forum.
Welcome to the real world.
