Gamers are gamers. It doesn't matter what you play or how you play it. Just because a gamer doesn't play an FPS game that doesn't not make them a gamer. Even if you play the Sims or Minecraft. Or even a mobile game or Candy Crush. It doesn't matter they are a gamer. For instance if I play Overwatch and I am playing the Team vs Bot mode (Training). I am a gamer. People like to insult people for playing a game how they want but that person bought the game and have the right to play that game however the fuck they want. If you don't like the way someone plays a game. Good you don't have to watch them. It's that simple.
