Here's an intriguing take on the "Take a Knee" controversy. Stephen Beale thinks that we need to un-militarize football and maybe other sports which are too closely linked to the armed forces.
Full Disclosure: Football is high on the list of things that I could not care less about. I've never sat through even one quarter of a game and I'm not entirely clear on how it's scored. This also holds true for hockey, basketball and most other sports, though my parents did make me sit through a basketball game once when my age was still in single digits. I have a mild interest in baseball although I'm not sure I can name one current player. When I've watched it, it has usually been for Vin Scully and now that's over.
I have no problem with anyone else loving it. You'd be amazed how much you can get done in usually-crowded stores while the rest of America is watching the Super Bowl. I just can't generate any interest in sports, especially the ones which involve men hitting each other. Also, I don't see how anyone could argue that football doesn't cause brain damage — to the players and maybe to certain spectators.
