I'm not reading 126 pages to catch up, but my take is that:
You can't take a slap shot on a goalie after the whistle without getting jumped because it's a dangerous thing to risk the goalie getting hurt, the play isn't live and the goal wouldn't count.
There's a legitimate reason why that's part of the code.
Therefore, you can't be butthurt about a slapshot on no goalie, while the play is live, and the goal counts. Because that's the exact opposite of the situation that everyone agrees violates the code.
Your feelings of insecurity are not part of the code, protecting a goalie is. Being "shown up" by a windup? Don't give away the puck. Don't be trailing so you have to pull a goalie. Be a man and accept defeat with honor.
