I remember there were polls about it, but I cannot find them.
This one user is convinced the users here are literally below the age of highschool. I'm 25 myself and remember seeing people above the age of my parents posting, so I wonder if there's information on the ~population across ages.
I’m 21, and despite what these people think, the vast vast majority of people my age are not communists, but rather just plain nearly apolitical liberals.
