I disagree entirely. Love is a social construct. Love is arbitrary and ambiguous at best. It was a concept created by man and therefore it only means what we want it to mean. By that logic it is meaningless.
I'm skeptical of even the existence of love in itself. Who can truly say that they "love"? Especially of another human being. I think that most of the time "true love" is neither "true" not "love"; merely an illusion of love, with other emotions such as desire, pity, compassion or admiration, and subtle combinations of many other emotions, being mistaken for "love". For this reason I also completely disbelieve in "unconditional love". "Love", as we define it, is always conditional, even if the conditions are not evident.
