The other post about censorship (and the reason it was started) got me to thinking.
What is so magical about the age of 18 that suddenly turns a formerly immature 17-year-old teenager into an instant adult? The "he or she is 18" argument gets used a lot, so it prompted to me explore the question.
While I'm sure there are some very mature 18 year olds out there, they are the exception to the rule in my experience. I often hear the justification that at 18, "kids" should be allowed to do X, Y or Z, even if they still live under their parents' roof and still are in high school. It's like that magic number has suddenly turned them into rational human beings able to make complex decisions without any help from anyone.
Personally, I have a family member who is a very (and I mean very) immature 19 year old. She's so immature that I don't really look at her and consider her an adult capable of making her own decisions.
So I ask, what is it about 18 that makes you (general) think that person is suddenly capable of making solid decisions and no longer needing the help of a parent?
