The NFL fines players for having extra decals, etc. They control what they wear and how they act. The should have done that with the first kneeler. When they did not it was all downhill from there. The kneeler could kneel and pay a fine. No problem.
NFL is show biz. The NFL harmed the business. It is that simple.
Vox Day has been writing about this stuff for a while. He is often an arrogant A-hole and I do not care about many of the things he cares about. He has three short books. SJWs Always Lie, SJWs Always Double Down, and Corporate Cancer.
He has many other books as well. NFL is also. Disney is going downhill. He described how they almost destroyed North Heights Lutheran Church in Arden Hills MN.
