Being expected to act a certain way at your job/while representing your company is nothing new.
This is not a freedom of speech/right to protest issue as its not being done on personal time. However, If NFL owners are ok with their employees doing it, then so be it. Its now up to you if you want to continue to support it or not.
However, having tax funded stadiums certainly adds some twists to this plot.
Quote:
Over the past two decades, the NFL has raked in about $7 billion of taxpayer money to spend on stadium renovation and building.
