"It is well past time to consign grammar pedantry to the history books."
Me and him be disagreein'. It's a given that language is always going to be dynamic and evolving. We see the proliferation of neologisms and common misspellings of words and phrases(e.g. cancelled) become so common that they end up being acceptable. There must be some sort of foundation however.
"People should not be stigmatized for the way they speak..."
Wrong. I can understand getting over things like "comprised of" and "cancelled" as being too overwhelming to eradicate. I can't deal with improper use of they're, their and there, double negatives and improper verb conjugation. Those should definitely be stigmatized
"I can't get no satisfaction" is a bloody song, not a speech. It works because "I can't get any satisfaction" doesn't roll off the tongue quite so smoothly. That doesn't mean we should dispense with the conventional use. Completely discarding grammar would be a quantum leap backward in effective communication, which is already suffering in the electronic age,
Irregardless of what he think language should be comprised of, do he thinks we's be wanting too tolerating verbal chaos?
