... not to be confused with pedants, of which we have plenty ..."Plenty" suggests we have "enough" pedants. Is that even a meaningful statement? To those who engage in and support pedantry, there can never be "enough" pedants: everyone should be a pedant. To those who prefer a less rigorous approach to everyday conversation, a single pedant is "too many". So how could there ever be "plenty"[1] of pedants?
[1] This should probably read "'a plenty' of pedants", although if using the pronoun construction it would work as "'plenty' of them". I imagine CRC will cite derivation to prefer one usage over the other.
