Balance in a documentary, what a concept

Mercator.net has an interesting article on a Canadian documentary called C-38 which examines the issue of same-sex marriage by having balanced interviews of both supporters and critics of Canadian Bill C-38. Michael Cook says the documentary demolishes the case for same-sex marriage. Seeing quotes such as What’s marriage? — "just a ring and a big spiel," made by one teenager shows the depth of misunderstanding of what marriage is. They didn’t redefine marriage in Canada because they never defined it in the first place. The documentary even includes two Bishops
and since one of them is Bishop Fred Henry you know that they didn’t cherry pick opponents that come across as idiots.
