This sums it up perfectly for me...
Nick Herbert, Conservative
"If marriage hadn't been re-defined in 1836, there wouldn't be any civil marriages; if it hadn't been re-defined in 1949, under 16-year-olds would still be able to get married; if it hadn't been re-defined in 1969, we wouldn't have today's divorce laws - and all of these changes were opposed. I know that the signal we send today about whether the law fully recognises the place of gay people in our society will really matter. Above all, I think of two people, faithful and loving, who simply want their commitment to be recognised, as it is for straight couples, and that in the end is what this bill is about."
