Or, "You are also responsible
for the results
of your inaction
This idea is one of the basic conclusions that I have come across in formulating my own personal philosophy. Picture this scenario:
You are standing next to a man with a gun. He has it aimed at another man. You can easily stop the man with the gun from taking the shot and killing the other man. However, you fail to do so, and the other man dies.
You are now complicit in the man's death due to your inaction. There may be justification for this action: the other man may have been dangerous, and the first man an officer of the law; you may have feared for your own safety by stopping the first man. While you may have justification, may have explanations for your inaction, you are still complicit. Notice that you are not being blamed - but also notice that you cannot achieve absolution; although you did not pull the trigger, you did not prevent it either.
Likewise, if you fail to stand up for your rights, you are complicit when they are stripped from you.
