I agree. However dating is not the legal problem. Having sex with someone you are dating is the legal problem.
Actually, both can become a legal problem. In some adults' eyes the mere
fact of people holding hands or having a PDA moment is sufficient to
cause suspicion that the relationship might be deeper, even if it is not.
I once heard a law student on campus say, "In a court of law it is
possible to even indict a ham sandwhich."
In other words, a mere accusation, even without basis, can be used
as a weapon to ruin the life of a person you don't like or don't
approve of.
On job applications, for example, do you know that the standard form
reads, "have you ever been arrested for any crime." In other words,
the mere fact of arrest is sufficient to bar people from employment
these days, regardless if the grounds for the arrest were unwarranted.
So no, I can't even risk holding the 20 year old's hand; because the
purpose of courts nowadays is not to determine the truth, but instead
to perform all manner of psychological warfare upon any defendant
who practically anyone doesn't like for any reason.
Taking a risk is impossible in today's legal environment.
Oh well.
