It's true food plots have collateral benefits for other wildlife, and it's also true that baiting can have collateral detriments--like disease transmission. But it seems to me from a hunting perspective, they both serve the same function, to lure an animal in for a shot. If it's not impressive to shoot a deer lured in by bait, I can't see how it's impressive to shoot one lured in by a plot, regardless of any benefits to other wildlife.
(I have no ethical problem with baiting, grew up where it was legal, and have done so. I now live in an area where CWD is present and believe it should be illegal here to reduce the spread of that disease.)
