This is why the Dallas Cowboys are my team; I love the attitude. Sure some grown immature snowflakes will call out Jerry Jones, but it’s his team, and he loves America.
Just as Jones sets requirements for his team, he expects commitment and loyalty. If he’s paying the salaries, why can’t he impose these rules on his team? If you have a problem with this, then you don’t want to be a Dallas Cowboy, or you should explore joining another team where they let you disrespect the American flag, but that won’t happen in Dallas.
