TBH even the Romans were saying that about us. Theres no smoke without fire
Saint Boniface wrote to Archbishop Cuthbert of Canterbury complaining about it
In your parishes, it is said, the evil of drunkenness has greatly increased so that some bishops, so far from checking it, themselves become intoxicated through excess of drink, and, by offering cups unduly large, force others to drunkenness. This beyond doubt, is a crime for any servant of God to commit, or to have committed; and the canons of our Fathers bid us remove or degrade a drunken bishop or priest, and the Truth itself says: “And take heed to yourselves, lest your hearts be over charged with surfeiting and drunkenness.”19 And Paul the apostle: 191 “And be not drunk with wine, wherein is excess.”20 And Isaiah, the prophet: “Woe unto them that are powerful to drink wine, and men of strength to mingle strong drink.”21 This evil indeed is peculiar to the heathen and to our race. For neither the Franks, nor the Gauls, nor the Lombards, nor the Romans, nor the Greeks have it. Let us crush out this sin, if we can, by decrees of our synods and by the ban of the Scriptures; if we cannot, let us by shunning and forbidding it wash our souls clean of the blood of the damned.
He still wasn't happy, in a later letter to Pope Gregory (I couldn't find a reference) he complains that the English are the most drunken nation he has come across. that was over 1,000 years ago, so old party pooper Boniface didn't have much of an effect.
So it's in our DNA, it's our cultural heritage. We should raise a glass and celebrate it
