Honestly, I dislike that sort of attitude. New people coming into the fandom doesn't "ruin" it. "Newer" people aren't any less intelligent than "older" ones. And no one's better for having been in a fandom longer than someone else. It's a relatively new game as it is, isn't it?

And you can't make presumptions like that when you don't even know the person you're accusing.

Your opinions have value and sense to them, but please try to be more careful and considerate next time...
