Love comes in many forms and you can love almost anything, if a man can love a woman romantically, a man can love his best friend platonicaly and call him his brother, and a child can love their pet in a paternal way, why can't a two people of the same gender love each other romantically. It doesn't bother anyone and the decreasing birth rates of the world had been proven to be because of the economy and health of the world, then why discriminate?
