Its not hard to find people against high fence hunting. With the fence all you gotta do is stay out of it. With corn it will change the movement of the deer and if you don't feed at all on your property then your neighbor is going to suck a good bit from you. So basically if it passes then everyone is effected.
If it's legal what's the big deal then. Other than you just choosing to gripe and moan about it. Your sinful neighbor would be legal. You could just as easily put out some corn, never mind that all your deer will then become nocturnal. What's the big deal other than some moral obligation against it. You go out to the Midwest on a guided hunt there's an above average chance there will be corn out, I bet you won't be shunning it then.
