Restating the obvious

From the Vatican's Zenit news service: "Marriage Is Only Between Man and Woman, Pope Reminds Canada." A short time ago this would have seemed like a tautological statement. Since it is no longer recognized as such, perhaps we can eventually expect to read the following headlines: "Historians determine Thirty Years War lasted three decades." "Meteorologist discovers flood danger associated with high water levels." "Medical researchers find deafness due to hearing loss."
