Of course Macklemore supports gay marriage. if you dont think so then you obviously havent heard his song same pag-ibig or heard of it for a matter of fact. in the song he talks about how his uncles are gay and he wants to legalize gay marriage . the song confuses a lot of people thinking that he is saying that he is gay . but you arent really a tagahanga of his if you dont listen to his lyrics from your heart
