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.
Somewhere between 25 and 30. Don't let these weirdos get to you lol. China, Cuba, Vietnam, DPRK and countless of movements around the world do not solely exist of highschoolers. It's just copium to deal with people having different views than their superior ones, of course.
Maybe not but communists do have the secret to eternal youth. Reactionaries suspect this and are jealous.
The directions to the fountain of youth are detailed in the back of Capital volume one.
