Re: The English language includes support for lists
The Oxford comma is a device to be used when needed, and not otherwise. For example, we know that traditionally crisps have been available in ready salted, cheese and onion, and salt and vinegar flavours. More recently the selection can include roast chicken, barbecue sauce and prawn cocktail.
Using the Oxford comma correctly requires thought, rather than blindly following a rule. I know this because my job title includes SLASH Proof Reader (although I also have the benefit of full time wage slavery).
