Quite, OG. Wishing to be seen as “correct” (not to be confused with “politrically correct”) in 2012 is seen as some sort of statement of superiority, smugness or class division. It is nothing of the sort. I won’t grace ludwig’s crass comment with the luxury of a reply, Nor will comment on jake’s fatuous contention that the flag’s correct presentation was the whim of some 18th century design consultants except to say this: far from being the result of a whim or “perceived wisdom”, the different widths of the white bands of the Scottish cross of St Andrew are displayed so as to give precedence to that cross (because it was incorporate into the flag first) over the red cross of St Patrick. It thus has a right and wrong side up which, whilst a bit more complicated than the Stars and Stripes, is nonetheless just as important.
The “...fact that nobody under the age of 40 (and many over) don't seem to care” is probably more due to the fact that those same people don’t even know that the flag can be flown upside down and less to do with any set of values those that do know hold. Unfortunately, rather than saying “thanks for pointing that out to me. I’ll make sure I get it right next time”, excuses have to be found for ignorance today and denigration of those with “unreasonable knowledge” naturally follows.
