Teens did get married a lot throughout history. Are they somehow retarded now?
Discussion
Yes.
They also fought wars, started businesses, took care of children, and did just about everything all other adults do.
Teens have always been young adults. Their current intense infantilization in the USA is brand new in human history.
Thats right but somehow modern teenagers are retarded and havent matured
The culture is poisened and ruined their minds
GenZ is beyond repair lol
We taught them to be that way.
This is 100% our fault.
As a father to gen-z children, hell no lol
Lie to yourself if you want.
Ok 
Statements prefaced with "As a father of...." are almost always bullshit.
because the topic is not your personal efforts or even your personal experience.
We as a society, teachers, other parents, grandparents, etc all created the atmophere in which they grew up. and basically Gen Z was expected to be childish idiots 'till their early 20s. Many of them are just doing what was expected of them.
