When a pitcher picks a runner off of first base, that is done with a dead ball?
I'll let your name calling speak for itself.
As you know, when the catcher throws the ball back to the pitcher after a pitch no one in their right mind would say “the ball is in play”. You are confusing the concept of “in play”, to an absurd degree, with the concept of a “live ball”.
As far as name calling goes.... the shoe seems to fit pretty well doesn’t it?
