Just because some publications use the word in that way does not mean the definition of the word should be shifted.
As to pedantry, you're the one who started arguing this clearly lousy definition is not lousy, brought up the OED, decided the OED is no good, finally acknowledged the existence of a broader definition but then somehow decided that it's, in fact, as good as identical to the narrow bad definition. I'll be the first to acknowledge I have a habit of getting involved in some deeply silly threads but I'm left utterly flummoxed by this Cirque-du Soleil-level display of mental gymnastics.
I just hope the authors of that lousy definition aren't holding your cat hostage.
You wrote this intending to say, "I'm saying the dictionary definition is silly, not that bigotry should mean what I want it to mean."
Instead, the sentence says, "The dictionary definition is silly, [because it's] not what I want it to mean."
