No No No not again! I only wish those Scots who object to Scotch as an adjective and the spelling of Scotch whiskey would spend a little time reading. Nearly all 19th century literature used 'Scotch' as an adjective and the Royal Commision on Whiskey (1908-1909) includes the 'e' throughout its definitions and there are many advertisements for the 1900s for both 'Scotch Whiskey' and 'Irish Whiskey'. And while we're on this theme, another myth which should be dispelled is the belief that Mc is Irish while Mac is Scottish. Again perusal of 19th century literature (and before) shows that Mc, which is used almost all the time when referring to Highland names, is actually M open quote, which looks like an apostrophe but turned round to look like a small 'c' (or superscript c).
Please, a little research before mouthing off those ignorant, unsubstantiated 'truths'.
