But its good to criticize and to complain when it comes to video games, television, film, and any other thing which we consume for personal enjoyment. Thats how you get your point out there. Its not good to do it by issuing death threats, of course, or by attacking the messengera much more common fallacy gamers tend to resort to. And of course some people will complain about everything and rarely offer up solutions. Misery loves company, or something like that.
My advice? Make your arguments solid. Make them more solid than your opponents arguments. Your arguments should be rocks to their scissors. Utilize data whenever possible, and avoid logical fallacies at all costs.
