There are people who hate people because they love people. Suppose being gay was the norm and you were prosecuted because you are a guy who just happens to be attracted by women. How would that make you feel? Think about that before you condemn others for loving someone. Please.
I bet you love someone and that someone loves you. It could be your partner or a secret lover. Your grandmother or your stepbrother. Love does not care about his or her skin colour, sexual preference, his or her religion, age or even the gender! Love is just love and has no labels. Why do we label love?
