A teenager from Northern Ireland has made an emotional appeal to his local government official, demanding to know why he voted against same-sex marriage.

15-year-old Darragh Tibbs, the self-proclaimed son of same-sex parents, released a video last week that sees the teenager openly asking his local Member of the Legislative Assembly [MLA], Gordon Dunne, why he believes that his parents shouldn't be allowed to get married.

Nearly six weeks earlier, Tibbs had sent Dunne a letter asking this same question. Dunne never responded, so Tibbs took the initiative to make the video.

In it, he reads the original letter, which implores Dunne to expand his sense of empathy and reconsider his position.

"I am 15 years old and a constituent of yours," the letter opens, "and I live just around the corner from your office. You voted no in the Marriage Equality vote last year—I want to know why."

He continues, "I’m the child of a same-sex relationship, and I can see absolutely no reason why my brother and I should be denied a secure family set-up. To me it seems perfectly reasonable that a democratic government should give all of its citizens the same legal protections."

"What gives you the right to take from my brother and me the right for legal protection for our family?"

For Tibbs, it makes no sense that Northern Ireland should hold out against marriage equality, which has spread to all of Western Europe and the rest of the United Kingdom. He concludes, therefore, that Dunne's refusal to acknowledge same-sex marriages is wholly personal.

"Gordon Dunne is a straight man, so when the legislation goes through, it won't actually make any difference to his life. The only conclusion were left is that Gordon Dunne doesn't support equality. He doesn't truly believe that absolutely everyone is equal, just those who he approves of."

In response to Tibbs' pleas, a spokesperson for the Democratic Unionist Party commented, "The party supports the traditional definition of marriage of one man and one woman...we don’t believe marriage should be redfined.”

Dunne has yet to respond to either Tibbs' video or his letter.
