The point is that the definition posted is narrow and bad. This isn't some obscure technical point, a debate about the proper usage of 'less' and 'fewer' or whether 'literally' literally means what it says in some odd case. All you have to do to convince yourself of its badness is read a newspaper or magazine or listen to a news report. What exactly would 'racial bigotry' mean if the posted thing was the only definition of 'bigotry'?

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.
