Vote with your dollars. Buy what you want to buy. If you like them, buy a ticket. Watch them play. You can let people know. If a lot of people just so happen to maybe dislike NFL players, they all may procrastinate from buying newer tickets, and that is a choice each person can make.
The problem is that they do these things to promote globalism.
