I'm not, there is a reason why this website was originally called cstrike - it was an era, but it's different now. CSGO looks, sounds, feels and plays differently now. Or do we pretend like TF2's first few years did not exist? What about WoW, Diablo 2, etc?
The rose tinted glasses concept is a logical fallacy appealing to emotion and anecdotal so i'm not gonna bite.
None of them, I'm just saying that game communities surrounding certain games can be considerably "toxic". CS always was, even when I played. Always has been, always will be.
