Most people here aren't mentally adults because they have missed out on a lot of "adult" things.
Many users here are unemployed, autistic, and other types of retarded.
We have low social interactions.
None of us have had sex.
We missed out on important developmental stages in life, young love, etc.
How do you expect people on here to have an adult mind when the only real difference between the mind of an adult and a minor is life experience such as experience with women, a job, managing a social circle, having children, etc.
Though I agree that most people here too stupid to engage in high IQ threads and low effort bait threads get more engagement.
