This is missing the point of what Leigh's talking about.
Not be to rude, but I don't really care what she thinks a gamer should or shoudn't be. It's just an opinion.
"Games culture is a petri dish of people who know so little about how human social interaction and professional life works that they can concoct online wars about social justice or game journalism ethics, straight-faced, and cause genuine human consequences. Because of video games.
Personally I think that's such a jaded narrow minded description of "games culture", formed and influenced by the certain type of behavior online that has given "gamer" the negative connotations we've talked about before in the thread
"Gamer culture" isn't divisive. Certain groups like to frame it as such, but today it's more inclusive and wide spread than ever. My dad plays games. My mom plays games. My younger brother plays games. My four year cousin plays games. It can be mobile games, or Madden, or indies, or freeware game jam entries, or the newest AAA titles. If you play games, you're participating in the medium, you're a gamer.
Now there are different ways of engaging in that hobby, the same way some people enjoy b-movie shlock or indie dramas or only watch blockblusters. But video games can and should appeal to a wide variety of tastes, preferences, age groups. Movies do, books do, tv does. Like every other form of entertainment, video games are enjoyed by a diverse range of people; only a fraction falling into that "anti-social petri dish" definition of gamer
So that's why I subscribe to the simple definition. You play games, you're a gamer. Simple as that
