This video was apparently made by NationForMarriage compares the merits of natural marriage against the dangers of gay marriage. It claims that their opposition to gay marriage is about biology, not bigotry. Although the video was released in 2012, it resurfaced after the US Supreme Court affirmed the right of the LGBT community to marry their partners. Anti-gay protestors are now using it as a rallying call to protest the Supreme Court ruling. Take a look @ Gay Marriage vs Natural Marriage = Biology Not Bigotry
