I think the implication is that people who are anti-woke are stupid so those are the ones you have to convince to use the Oxford comma since intelligent people already see the benefit.
Of course I meant it. The OC is redundant. People who use the JFK/Stalin anecdote are demonstrating a reliance upon memorization rather than logic as a basis of syntax.
I think the implication might have been that stupid people will incorrectly use it overemphatically, not that he is against the comma itself, but i could be wrong
