Anyway, complaining is fine as long it's done in a mature manner, and if you don't agree whatever issue the complaint bring up, feel free to counter it with your arguments. However, when you complain about complainers, you're not targeting their argument, but their person. And personal attacks are not allowed on this forum.
Not to mention it starts a never ending cycle where complainers complain about the complainers who complain about the complainers who complain about the complainers who complain about the complainers and so forth.
