Every NFL stadium has 8-10 NFL games a year...

Maybe a couple playoffs. Out of 365 days they have less than a dozen games.

Like you said, there's a huge demand for those. But the bulk of tickets are for concerts and other shit, that is where pressure is best applied. Because there's lots of other reasons to boycott stadium concerts anyways.

Like, that's the great part of living in dystopias, there's never just one reason for people to coalesce around a single topic.
