No. Simple verbal slights are only actionable if they are aimed at specific persons or at specific and reasonably small groups of persons. There is no law against dissing some huge amorphous mass membership in which isn't defined, or can't be ascertained, with anything even remotely approaching conclusiveness. "People not in the IWO who've read some IWO material once" is about as amorphous as it gets. You'd only make an ass of yourself trying to get this prosecuted.
I think your most dignified option would be to quietly walk away.
