My assumption is that if you're in the meeting, it has some adjacency to your work. This isn't about calling on the daydreaming kid in high school Spanish class who _has_ to be there to graduate. If you're in the meeting, it should be applicable to you and you should be ready to give some input; even saying something like "I'm not sure, need more info", or "don't have anything to add" is a valid and acceptable answer.

If the meeting isn't germane to your work, why are you in it?

I know people who do this because they're genuinely trying to get input from a broad set of people, some of whom will never speak unless they're asked directly. It doesn't have to be a mark of an alpha trying to beta everyone else.
