I haven't heard anyone say it's trivial; except for you.
The Law might be "a ass", but it shouldn't act like it.
If 13 is too young for consent, logic and reason should indicate that it's equally too young to be labeled a "registered sex offender" for life.
For precisely the same reason.
Hm. I'm sure you'll understand if I tell you that some of the posts on this thread seem to me to be doing just that. Contrary to what some on this thread appear to think, the police reports indicate that it wasn't a case of "grab ass, like all kids do." And yet that's how it's being presented by some.
