Compare tennis to badminton. For example, consider the All England championships. Badminton's premier tournament, somewhat akin to the Wimbledon of tennis. https://www.youtube.com/watch?v=TP2ltjz4C04 Listen to the crowd. No "hush" before service. Full blooded screams at every shot. Look at the players. Body shots , even head shots are routine. Have to deal with the most guttural screams and unfriendly crowd. Look at the coaches. No complaining about coaches directing instructions to the players. In many ways, I think tennis is really wimpy.
