The one “grammar debate” I don’t get is the Oxford Comma debate. Of course there should be one. There’s no argument for leaving them out, and a million obvious ones for including them. There is no debate. Include it, barbarians.
I’ve never gotten this either. Even if the lack of a final comma creates ambiguity only one time in a hundred, why not use it for that one time in a hundred? It’s completely harmless the other 99 times, isn’t it? Seriously: what’s the argument against the Oxford comma?
