My argument has nothing to do with right or wrong. Most employers now will force you to sign something that basically says "if you say shit on social media that will make us look bad, we can fire you immediately". I imagine that the NFL does too. If I want to keep my job, I do what they ask me to do, and above all, I use common sense and try not to say anything that's going to make them look bad, despite how "oppressed" that makes me feel. Right or wrong, it's the employer's choice. You can stand up as an unoppressed person that says whatever they want, whenever they want, and not collect a paycheck.
