I strongly agree with my hon. Friend.
I believe that many who do not share that view nevertheless have a principled concern that gay marriage would mean redefining the institution for everyone, yet Parliament has repeatedly done that. If marriage had not been redefined in 1836, there would be no civil marriages. If it had not been redefined in 1949, under-16-year-olds would still be able to get married. If it had not been redefined in 1969, we would not have today’s divorce laws. All those changes were opposed.
