Linguists get descriptivism drilled into them from day one! If anyone who goes on about what is "right" I would highly doubt they were trained as a linguist. You could perhaps instead mean "standard" instead of "right" - that they're describing a standard dialect, which doesn't meet reality. That could be true, I'm sure it is in places. Btw, I'd be interested to know how many parts of speech the CGEL describes. Anyone got easy access?
