I apologize for hurting your feelings!
“as long as he or she is legally allowed to possess the weapons in both the state of origin as well as the destination.”This (FOPA) does not provide any protections driving from MD to DE if the firearm is a no go in DE. I believe that there needs to be at least 3 states in the trip for FOPA to apply.
If it were not legal in PA (and good in DE) and you took a circuitous route from MD thru PA to DE FOPA would apply there.
