To nobody in particular, but to anyone who would feed deer . . . I don't really want to sound heartless here, but in my area the deer are so overpopulated that I'd never consider feeding them to keep the populations up. We have constant battles between car bumpers and deer. Crop damage is an issue. Deer in the suburbs getting lost in the housing tracts and busting through windows that reflect trees. Our deer populations are probably 10x the historical highs, there are very few predators to cull the herds other than hunting season. The occasional coyote will take down the weak ones, but the combination of coyotes and hunters is not enough to control the population explosion we are facing. If it keeps up, we will be seeing mass starvations or serious disease issues. Either of those will be horrible, but out of control populations EVENTUALLY get a dose of some sort of reality from nature.
All that said, I love to watch them, I don't hunt them, and they are beautiful creatures. But we (humans) decided to get rid of their natural enemies in many areas and now we are faced with some serious issues.
