With your temper, I can see why they took it away.
The reason sporting equipment is not allowed in the cabin is the shortage of space in the cabin and the overhead bins. There a few vertical lockers that were used for golf clubs but those days are over. The flight attendants have a hard enough job getting people to just sit down without having to find a way to make all of this stuff fit.
I was told once that a cue can be used as a weapon, that's why it's not allowed on the plane.
I can only imagine the airlines would love to allow you to bring a cue on their plane so they can charge you $50 each way.
