In Texas, feeder watching is a way of life. I've found, on my own 10 acres, that if your land is in the right spot, a feeder can be quite productive.
However, it gets boring. I'd much rather spot and stalk out west, but white tail in the woods and prairies don't lend themselves to spot and stalk. Feeder watching is the only way. But, that's why I go west to hunt when I can afford the time and money.
Baiting hogs at night is legal here in Texas. I do it on occasion. Not a big deal and fun. I don't consider it unethical.
On the subject of "enough gun", what about archery, where it is expected you'll have to blood trail the animal because he only dies when he's bled to death????? I still consider it ethical. If he's stupid enough to come within bow range, hey, he gets what he deserves...
I don't bow hunt, can't shoot the things with my eyesight in my strong side eye.
The ONE thing that sort of irks me, I answered an ad in the paper once for hog hunting just south of San Antonio. When I got there, it was a 700+ acre high fence ranch with exotics. The hogs were plaguing the place and you were allowed 3 under 100 lbs on a two day hunt, what I was looking for, meat hunt. It was only $180 for the hunt. I had great fun killing my three hogs. Anyway, on a tour of the ranch when I first get there, the guy is feeding the exotics. I mean, there are red stag, muffolon (sp?), black buck, this and that and they come out of the woods like the pied piper following the jeep. The guy says, "Yeah, when I bring exotic "hunters" out, I like to let 'em out down the road so they can make a "stalk"." Now, this guy was serious! I shot one hog on the run, he fell a few yards into the woods, when we went after that hog, and just after the shot, this red stag comes walking up for a hand out!
Later, I'm walking through the woods kicking brush piles looking for my third hog when the sheep/goat of some kind, probably Barbary sheep or something, one of those curly horned looks like a big horn sorts is walking toward me down the same trail. I was camoed out in my 3d, so I stop motionless. This thing walks right up to me on the trail sniffs me, turns around, and walks off! What the heck kind of "hunting" is THAT?! The hogs were wily enough and the deer stayed to cover pretty much, but the danged exotics were friggin' PETS. It's like walking out in the woods and shooting a cow! I don't call that hunting, ethical or not.
