Why would it be wrong for them to wait a few years until they are both of consensual age before engaging in a physical relationship? If it truly is love for the sake of love, then a couple of years should make no difference at all.
You really believe that? This is wasting a few years, nothing more. Wasting a few years of your YOUTH. Sorry, but if someone suggested me to do so... well, think about it yourself. You love a man, you WANT him, you want to know him in every aspect. Yet there's a boundary that for few YEARS you can't even kiss him. Oh, it is soo cool sweet-talking about true love, but if you stop dreaming for a bit you'll understand, that human relationship are complex, but they are still logical and demanding. They just can't go on for ever without sexual experience, and I should point out that by our laws even TOUCHING an underaged person is an offence. Even thinking of him/her as your loved-one is offence. Let alone kissing, and definitely not sex. Under such strain 99.9(9)% of relationships are bound to end. Love needs fuel, and this fuel is the instinct of breeding, which can only be maintained by sexual activity - touching, kissing, flirting, fucking. Without it flame goes off and in the best case turns to just friendship.
Really, why can't they wait? Because there should be limits to ideolism, dear.
Everyone seems bent out of shape about the legality, and whether or not its right. Let me post a "what if" scenario. What if the laws governing kiddie porn didn't exist?
Now, let's see.
1) no one supports engaging unpubertated children into porn - this is unquestionable.
2) An underaged pubertated teen is still dependant on his/her parents, and that instrument should be used by them to prevent any stupid moves. Just like it's used to prevent getting a tatoo and other stupid things. Most parents are able to control their children by other means than outright forbidding something.
3) The problem is the law. Noone's saying an underaged pubertated teen should be considered fully adult. We are merely stating that the right to have sex whenever and with whomever he/she wants should be given to them, They have their own head already, and sex is not a threat anymore, that can cause unexpected children. It's not a prescious thing to be treasured untill marriage neither. Sex should be stripped out of age limitations, IMHO. Porn is the other thing. A forbidding laws to drink alcohol, drive a car or shoot in porn can still be preserved, I'm not against it. Those are still threats. Alcohol is a threat for health, Driving is for others, and porn is for image and reputation. But sex - sex is not a threat to anything anymore. Instead, as I stated already, forbidding laws is more of a threat, because teenagers already treat sex as something natural and easy, but forbidding laws make all kinds of problems, starting from buying a condom, ending up in going to a sexual consultation. We'v reached the limit where it's actually already more harm than use.
