Rape is already against the law.
No need for a special subset of it.
When is a law not a law, Elsie? When it’s not enforced!
Seeing that the likes of NAMBLA is allowed to exist and operate to this day and male homosexual marriage clears the way for them to adopt little boys (they are not behind closed doors teaching the boys math and science I assure you), and even male Hollywood actors who have gone to law enforcement to report their own sexual assaults only to be ignored (by big media as well), it would seem something more needs to be done to acknowledge what is occurring and stop it.
What you state sounds nice, but the reality says otherwise.
