Plenty of experienced hunters hunt with semis like the Remington 740/7400 and Browning BAR. Training and practice are more important than rifle action.
The worst encounter I had in the woods was a woman blasting away with her Win94 like it was a M60. And most of the stories I hear of hunters killing innocents or each other are one shot with a bolt action and scope. The bolt action did not transfer an ounce of common sense into them, nor have I seen a semi instill spray and pray in a hunter.
I personally prefer a bolt action but I can understand if another hunter prefers a semi, pump, lever or single shot.
