Here is a general list of responses when someone decides to stir the shit-pot.
Videogames are stupid.
If we are to judge other mediums by the standards we judge videogames, then yes, all art forms are absolutely stupid. if we look at impressionism, hell, look at Jackson Pollock he has some cool-ass art in my opinion, but to an outside observer, it looks "stupid". Or better yet, no one can deny all the sociological and political situations confronted in the Harry Potter saga, right? well, Harry Potter is a story about a kid who has a scar on his forehead that helped save him from the most overpowered death spell since being locked in a room with John Wayne Gacy. Stupid, right?
Videogames create Serial killers.
No... Just no... anyone who knows an inkling of psychology can tell you that the formation of a serial killer takes years, and is due to mistreatment, psychological disorders, and generally having a VERY messed up childhood. Videogames have nothing to do with that. Your killer probably also has seen something like Matrix or High-paced action films, i don't see them getting blame?
Videogames are a common denominator between most modern serial killers.
because Videogames are so widespread now that line of thinking is flawed, I'm sure they also found bread and milk in their house but no one give bread and milk industries shit. Plus I'm sure Jack the Ripper didn't have videogames to pump him up for murder.
You just sit there and stare at a screen.
Sorry to break it to you, but that's also what watching movies and shows entail, at the same time, reading a book makes you sit still for hours at a time staring at pages of tiny block letters. I that really better?
Games aren't educational.
Unfortunately, games really haven't been around long enough to be able to argue this as I'd like, and i don't have many examples, but i can certainly point out that not only are there very educational games out there, like Portal, Mass Effect 1-2, Assassin's Creed 1-2. But also, they don't HAVE to be educational, maybe games can just be? i don't think Cowboys and Aliens was very educational, but it was pretty fun to watch, does that mean films should burn in hell for not being so educational?
Back on Topic, most of my family dislikes that i play videogames, and give my a lot of crap for it, but whatever, they're just really stubborn on this.
