[lotyrin]

Linguistics should seek to be descriptive rather than prescriptive. The field should, primarily, seek to describe language as used. Prescriptions can be useful and should be made if they improve a language's ability to provide clarity (please mind the theirs and toos, and sometimes an Oxford comma would clarify your sentence) but they should be held to be mere suggestions and not authoritative mandates.

The idea that there is only one correct way to use a language and that it is determined in academic circles and should be enforced on the masses is inherently based in illegitimate authority and social exclusion and is not a social force for good.
