I'm okay with Otaku culture in general, I remember loving a little diatribe that was in Log Horizon where a character remembers being told that playing games is wasting your time and you should be doing something more productive instead, and the takeaway is simply, "It's my time, if I'm enjoying myself, then the time isn't wasted."

Fuck yes, dude! I can completely agree with that!

It's more the "my sense of self is defined by that which I consume" that worries me.
