*The point is that these are different things. "Same-sex marriage" is what it actually is. "Equal marriage" is the campaign for it (i.e. to make marriage between people of the same sex equal in law to marriage between people of the opposite sex), which is why you are getting a lot of ghits for it at a time when people are campaigning for it. This article is about "same-sex marriage in the United Kingdom" as a whole, not just about the campaign for same-sex marriage. As such, it should use the current title. As a British person, I can assure you that "equal marriage" is certainly not the common term for the marriage itself in this country. Neither do I think it is intended to be.
