13 year olds are also different from 19 year olds
and 13 year olds are different from 7 year olds
I have seen people literally argue that a romantic relationship MUST be abusive because one of the lovers is only 19 and therefore "still a teen" ... the dogma that says teens are children is absolutely false and it is damaging the hell out of young people.
This 4 minute vid explains it pretty well. https://youtu.be/12J1f0Zqaqw
Do people really believe that 20 year olds are children and no one ever in the entire history of the world ever noticed this, and the only people who ever got this right are in the USA in the last 20 years?
That is just astoundingly ridiculous.
