I have zero problem with these people and neither should you. Your example is immature and extreme, bearing no relevance to the topic you bring up.Toilet said:
Overall video games is experiencing a commodification of a culture where what used to have meaning is being sold en masse and this makes people who are actually part of that culture mad. It would be like if I played 10 minutes of basketball and called myself a professional athlete and tried to fit in with other 6'4" basketball players.
The best example is the punk rock which was anti establishment but now you can buy punk rock on iTunes and buy spiky belts in Hot Topic.

People want to say they like video games and dressing up as video game characters? Let them. In no way should it affect or bug you, they're not forcing you to do anything nor are they radically altering geek culture.
