Disconnect battery when parked?

Us humans given a chance to "argue" and we jump at it lol
Can't group me in we (although I am human, I think. Jury is still out on that one).
Just ask my wife. I'll turn and walk away from what might become an argument before it begins. As far as this forum, I will do my best to show someone the error in their ways.
I'll go ahead and share one more reason why the neg' and not the pos' should be removed... A end wrench on a neg' battery terminal can accidently contact a metal chassis ground. No sparks. I saw a battery explode in a guys face because he had his wrench on the pos' cable end. A guy named Curtis and I grabbed the other guy by his legs and dragged his face all around in the sleet and snow. Damage to his face and eyes was minimal.
