Then why did you make a generalization in the first place and keep making it? I didn't introduce the term to the conversation you know.
Let's ask a simple question: would your conception of a "serious gamer" include literally anyone who plays PC games at all? You have to have some line you're drawing somewhere right? Well, I can't read your mind so I'm using my own line, which is drawn where someone considers gaming to be a very high priority to them, and it seems unlikely to me that that kind of person is willing to make that trade off for some nebulous concept of "privacy".
