Replace "gamers" with "book readers" and it should become obvious why this is not an insightful comment, but rather an expression of some kind of existential angst mixed with outdated stereotypes. Gamers ceased being a distinct consumer group when the medium of games went mainstream and ceased to heave anything resembling a coherent subculture.
From my personal experiences absolutely there is a group of people you could reasonably call "Gamers" and performing dramatic consumer entitlement is definitely part of their culture!
How do you know if someone posting a random nasty comment on the internet is a "Gamer"? How do you know if someone posting a nice comment is not?
You're projecting identity on people and then project attributes onto that identity. Most likely you're unconsciously selecting who to project the identity onto based on the same attributes. This creates a feedback loop. This is literally how stereotypes are constructed and reinforced.
What is weird about saying that? I'm very entitled book reader. And if the rest of book readers were as entitled as me many supposed literary geniuses would sell 5 copies before the word got out how pointless and horrible their creation is.
