Love is supposed to be a generic term but we usually associate it with romantic love. Romantic love is distinguished from the rest of its cohorts because of the specificity of the age and stage of life when it arrives, its overwhelming tidal force when it takes over, the creative outflow it unleashes, and the subjective blindness it induces by a combination of myopia and presuppositions. There is no sense in fighting it since it holds our genetic reins.
Is it bad and harmful? The answer will depend on whether you are holding a knife by its handle or its cutting edge. Holding by handle implies your ability to master the hormonal storm by which the romantic love has besieged you, and tame it until your navigation comes under control. It is more difficult than what it appears to be because the tempest is blown by Mother Nature herself who wants you to multiply without any further procrastination. Delay for her is dangerous!
