Being a "pacifist" (believing that war and violence are unjustifiable) is a philosophy that some embrace. Being a "pacifist" is a real thing but being a "passivist" isn't. Passivist is not a word. However, there are many people who believe that being passive is a philosophy and thus have become "passivists". Being passive may be fine in certain aspects of life but not in athletics. I have never found myself or another coach instruct an athlete to "be more passive". Sure, patience, or calm, or deliberate, or trusting, but not passive. In fact, the opposite is the case. One of the big problems is that most feel that the solution to passivity is aggression. Cheerleaders even have cheers which encourage athletes to "B-E A-G-G-R-E-S-S-I-V-E". However, aggression isn't the answer either (as aggression involves the intent to harm someone). And that is why most athletes struggle with giving the correct amount of intensity in their sport and erring on being too passive. When a coach tells an athlete to "Be more aggressive", the athlete doesn't know what is being asked of them, nor do they know what to do to remedy the problem. We don't need to be angry/mad/upset or "fired up". We simply need to be intense. We merely need to understand that passivity doesn't have a place in most sports but intensity does. Calm has a place but passivity does not. Being "assertive" is what we must be pursuing. Being assertive refers to being intentional and intense at the right moments. I don't know an athlete who wants to be referred to as a "soft" athlete. Soft is the result of not being intense when intensity is a requirement in athletics. The goal today is to find ways in our training/life that being more intense is beneficial. "You can't be so damn passive" Daniel LaRusso - Karate Kid III.
