"But if a state issues a hunting license to such a person, then in effect the state is giving that person their blessing."
I don't know of any state that assumes any type of responsibility for a hunter, any hunter, just because they sell somebody a license. The sale of licenses is all about fees - money to run the fur & fin agencies - and not about the blessing of an activity. Call them and ask and they'll tell you that.
And once again I'll point out that you don't need a license to hunt in VA on your own property no matter if you're blind, deaf or so-called normal...AND...you don't need a driver's license to drive on your own property either - even if you're blind or underage.
