You have to understand where we're coming from on this. The present-day law on gay marriage was changed due to the wording of the original law, written in a time when gay marriage wasn't even being considered, which happened to say something like "two persons" rather than "a man and a woman".

The Republic will not fall because Adam marries Steve. What consenting adults get up to on private property is no-one's business but their own, certainly not the Governments. But it is under threat when law is made through legal chicanery rather than the democratic process. That is why Conservatives are up in arms about gay marriage.
