Well, start waving and yelling, because it is the so-called Oxford comma and it is a lot more dangerous than its exclusive, ivory-tower moniker might suggest. There are people who embrace the Oxford comma and people who don't, and I'll just say this: never get between these people when drink has been taken. Oh, the Oxford comma. Here, in case you don't know what it is yet, is the perennial example, as espoused by Harold Ross: "The flag is red, white, and blue." So what do you think of it? Are you for or against it? Do you hover in between?

Don't pessimism and caution naturally go hand in hand?

In the family of punctuation, where the full stop is daddy and the comma is mummy, and the semicolon quietly practises the piano with crossed hands, the exclamation mark is the big attention-deficit brother who gets overexcited and breaks things and laughs too loudly.

The rule is: don’t use commas like a stupid person. I mean it.

What the semicolon's anxious supporters fret about is the tendency of contemporary writers to use a dash instead of a semicolon and thus precipitate the end of the world. Are they being alarmist?

Truly good manners are invisible: they ease the way for others, without drawing attention to themselves. It is no accident that the word "punctilious" ("attentive to formality or etiquette") comes from the same original root as punctuation.

Offence is so easily given. And where the 'minority' issue is involved, the rules seem to shift about: most of the time a person who is female/black/disabled/gay wants this not to be their defining characteristic; you are supposed to be blind to it. But then, on other occasions, you are supposed to observe special sensitivity, or show special respect.
