Why everyone is so toxic?

Hello there, been back on this game after a literal decade, everything feels nostalgic and amazing yada yada yada, but is there a reason for everyone to be this rude or straight up f***ing toxic over a “dead” game? I swear it’s like two weeks back on it and got a lot of people swaying so much hate acting like it’s a matter of life and death. Have they got the chance to touch grass somewhen in these ten years
