An 18 year old brain is not the same as a 54 year old brain. You don't suddenly become an adult when you're 18.
In fact, it's that reason why so many teenagers are out on the streets, because their parents threw them out at 18 years old. "You're an adult, get out of my house!" It's severely messed up, 18 year old brains are still growing. Your brain doesn't stop maturing until you're about 25-30 years old!
How many high school students were dating college freshmen back when you were in school? I don't know about you, but it was the thing back in the 1990s. It was pretty common to see 16 year olds dating 19 year olds...they got together when both were in high school, and then continued the relationship. Many of these people ended up married. But, of course, they had to hush it up when the older student got 18 and up, because the legal laws are so ******* STUPID.
And as far as 14 year olds having sex, they will. It's better that they be in love with someone with a 3 or 4 year difference, even if that person is 18, rather than a 54 year old grandpa pedophile. And did you disregard my assertion that the only reason the 18 year old is being charged is because the parents of the younger girl have something against being gay? Because they even admitted to it! "Lesbians are sinners..." Nice message to send to your sexually confused daughter!
And also, the only reason that the legal age was lowered from 21 to 18 was so that the draft could be in place. They wanted to send off 18 year olds to war, so they lowered the age to 18 so that they could.
Again, it has NOTHING to do with maturity, or being an adult.
