Before Voat I didn't even know being a concern fag was a thing. Urban dictionary doesn't even recognize the term. Actually, the kneeling thing was the last in a growing list of complaints about the quality of the NFL product over the last decade. The straw that broke the camels back. But still, I did mouth off about boycotting the NFL on multiple occasions.
And it isn't that I won't watch the NFL, I have watched several games since the Steelers (my old NFL team) decided to stay in the tunnel during the anthem, but like it is a Sunday afternoon, hanging with the wife at the house(getting over a cold) and don't care that an NFL game is being played.
In retrospect if it took being a concern fan to get over the programmed need to watch a sporting event, that is okay with me.
