Unless your reasons are QDM I just don't see the difference. It would seem that in many areas you might even benifit the herd if the fawn is sporting spots too late in the season to be a good bet to winter thru. If it's legal and you want to shoot it go ahead.
It'slike some guys have got a Bambi thing going on.

I have in the past shot a deer that did not have spots but only required a little force to put into the fridge crisper drawer.
I just hope none of you folks drive anymore carefully when the car in front of you has a "Baby on Board" sign than you would otherwise.
