"Love is By Definition Radical"

Michael Voris, a Catholic and fellow ND alum, produces and hosts a show known as The Vortex. For the past couple of months I've been watching it regularly. In it, he covers many topics of interest to Catholics, particularly information about people and movements that try to distort or discredit the Catholic Church's moral teachings. A couple of weeks ago he put out an episode called Radical, Man. Radical. It was about Catholics who don't want to speak out about the truths of the faith in order to save others because it would be too "radical" to do so.

There were many good points made in the episode, but one quote in particular jumped out at me as being relevant to all people (not just Catholics) from a natural-law perspective, especially in light of some of the responses to my post yesterday about contraception.

The quote was as follows:

When you love anything, you by definition love it radically. If you don't, it's not really love. It's warmth, or fondness, or affection, or nostalgia, or duty, or obligation - call it whatever you want, but it ain't love. What parent doesn't love their child radically? What spouse doesn't love their spouse radically? Love is radical. It's why you get out of bed in the morning. It's why you labor throughout the day. It's what directs your thoughts and your heart.

Would our culture agree with the statement that "when you love anything, you by definition love it radically?" It would seem not. I mean, I so often hear from people that they need/want to have sex with their boyfriend or girlfriend because they "love" them, yet they're not sure whether they want to be together forever, so they're not going to get married and are going to use all manner of hormones and devices to "protect" themselves from the possible effects of sex with one another. So, it's clear that they don't view love as a free, total, faithful, radical, selfless gift of one person to another. If they did, they'd be committing to that person for life, and they certainly wouldn't feel that there is anything in the other person that they need to be "protected" from.

So the question becomes: When such a person says that they "love" their boyfriend or girlfriend, what do they really mean?

Is it really possible to understand love in any way other than how Michael Voris describes it?
