The below quote is why non-religious people and most sensible Christians dislike the way any Christian groups or activists talk about gay marriage. from the bbc
Andrea Williams, chief executive of Christian Concern, said: "We can't just redefine an institution - redefine something that always has been - because we say it's something that we want.
"This is actually very self-centred. This is not about rights, it's about seeking cultural dominance and seeking to redefine marriage for all of us."
No Andrea, what is very selfish is to refuse to redefine things that are within our grasp to redefine because they work for you and your prejudice. Marriage is not a religious institution any more, if it were then no marriage at a town hall would be legal. So basically stop being such a close-minded idiot.
