But actually, the post from that blog I came in to share was this one, which is about flag pedantry.
As @Mangetout and most other Brits will know, there are people who are sticklers for the correct terminology for the UK flag. Most Brits would call it a Union Jack. Nowadays however, there is a reasonably well known rule that it is only a Union Jack when flown at sea. On land, we are told, it is correct to refer to it as the Union Flag, and Union Jack is a terrible howler.
This is bollocks, as described in this exceprt from a radio interview between host Paddy O’Connell, and Graham Bartram, Chief Vexillologist of the Flag Institute:
O’Connell: So, the argument has been: the Jack flies on a specific ship on a specific place, and the Flag flies on land.
Bartram: Well, that’s what some people say, but in fact the two terms have been used throughout history completely interchangeably. There are royal proclamations that say Union Jack, there are royal proclamations that say Union Flag, and sometimes when they say Union Jack they’re referring to land, and sometimes when they say Union Flag they’re referring to sea. So I think it’s up to you to decide what you want to do.
They then moved on to the nature of the supposed rule that Bartram was debunking. O’Connell perfectly played the part not of the rule-monger but of the ordinary person who vaguely assumes that some sort of rule-mongering must be right. Much of what follows could have appeared in any number of conversations about correctness in language:
O’Connell: When did it become convention for vexillologists to prefer Jack and Flag as two distinct items, or two distinct designs?
Bartram: I think it’s probably in Victorian times that they actually decided, that certain vexillologists decided that it should properly be called one thing in one circumstance and properly called something else in another circumstance. I think the Victorians were very keen on having rules about everything.
O’Connell: Well, so are some of our listeners. What are you doing to these rules?
Bartram: We’re not doing anything to them, we’re just saying these rules are made-up.
O’Connell: By you?
Bartram: No, no. They’ve been made up by just people writing one thing in a book, and people then read it and say ‘that’s the law’ when in fact it’s not the law.
O’Connell: Are you seeking to do what the Oxford English Dictionary did with “literally”, which was to say we could use it figuratively? You’re backing the public: if they say Jack, that’s a Jack, or a Flag.
Bartram: We’re backing the fact that the flag has no official name, and you can call it a Flag or you can call it a Jack, and which one you use is entirely up to you.
This illustrates the worst of the pedant mindset pretty well - make up a rule (or accept a made up rule without critical thought) and then cling to it dearly.
But an even better illustration came with one of the listener comments, which really is a perfect distillation of the pedant mindset, especially given that it was made in the teeth of the revelation that rule is a mere confection.
We need to know the difference between the Union Flag and the Jack because it’s useful to know how knowledgeable someone is to get an idea of whether they know what they’re talking about.
It doesn’t matter whether the rule is actually right. The important thing is to have a rule, so that you can judge others and yourself according to whether they follow it. And, not coincidentally, to appoint yourself as the person who decides whether others know what they are talking about. Which is a very comfortable place to be!
