Well, those numbers, while still lower than the US number actually have gotten wrose since gay marriage was legalized. Trends matter, too.
I'd also direct people's attention to countries like Norway and Sweden, which legalized gay marriage or civil unions and now see 50% of first children born out of wedlock.
I'm not so sure how these married gay fellows are able to have children out of wedlock 
I think the point he was making is that once homosexual marriage is legalized, "family values" are disregarded and people start having their children out of wedlock. A correlation of some sort.
