Yes. We're in a war. Ignoring it doesn't make it go away. Most of us figured this out before our tenth birthday.
Judo is not ignoring a fight. Judo is using your opponent’s attack against him. And Judo is not just standing there after you have flipped your opponent and then wait for him to attack you again. Once you have flipped him, you put a choke hold on him until he gives up or passes out or dies. What is foolish is to see your opponent coming at you with a baseball bat and putting your hands down by your sides while you hope that the bat breaks before he kills you. Since you’ve decided to be snarky, it appears that you haven’t reached your tenth birthday, yet.
