Although humans are diverse in regards to lifestyle preferences - deep down we are one and the same (living the human condition) where love and, its opposite, hate (and all the concomitant superficial beliefs/ identities/ feelings) are common experiences.

Also, the feeling of love (be it romantic or filial or whatever) doesn't last, and is not stable; people who profess that are usually the ones who have arrived at some kind of compromise. Right in this very thread you will find someone who redefined love to be an "act."

Above all, no matter what one's lifestyle preference is - love hurts. So why the reluctance to question love itself? Why the continued investment in boasting the superiority of love (all that sad love songs have a tinge of sanctimony to them)?
