I think it’s good for them. They’ve already spent the money. What options are there?
The only “good” option to keep seats empty is to toss the tickets (burn them, so no one else can get them).
Well, there goes your money. Next option, use them, and boo; bring mean-spirited signs. Maybe toss some cans on the field. Face away when they pull their “whoa-is-me-blacks-oppressed” garbage. Show them some reaction, some disapproval.
And then avoid buying tickets from now on.
Hire a message plane to fly over the stadium with a brutal message like:
“Trump Rules NFL stools”
