You are welcome to share your concerns. We encourage it. I encourage it. There will be no lj retardness here, and while I will not go so far as to say this place is a democracy (mods do have the final say) it is a republic, we do want to know what you feel.
Saying that I have to say that none of the sceniros you brought up in your post really fit under this rule, and would be allowed. And I have to say that your comment about the Hobbits I hope was in jest. Because, ummmm Middle Earth is not real, and therefore is not a place were you can conceivably live. This means that the shires 33 year old age of consent rule should therefore have no bearing on you or the members of this community. :)
