But you're so wrong. Emotions are the opposite of rational. You have much less control over your own actions than you realize, and definitely very little over your feelings. If that were not the case, depression would just not exist.
Read up on neuroscience. It may open your eyes to the reality of being human.
Of course. (If not "the opposite", at least they are not rational.) But - again - neither love or hate are emotions. They are decisions. Of course, they may be made irrationally (like many others) or under the influence of emotions (like many others), and a lot of things other than emotions and rational analysis may influence these decisions (like many others) to some degree. But that is beside the point.
