Understand "talk about [text]" as talking randomly about. Talking randomly about is an action applying to one topic. Carry out talking randomly about: say "Mostly you're interested in [the list of subjects]."
A subject is a kind of thing. Assyrian vowel sounds, designer handbags, and instant run-off voting are subjects. Understand "linguistics" and "mute" and "stop" as sounds. Understand "prada" and "tods" and "coach" and "carmen marc valvo" as designer handbags. Understand "reform" and "election" and "election fraud" and "two-party system" and "Diebold" as instant run-off voting.
