I think the song is anti-fox propaganda.
How can a fox steal a goose, when nature has no concept of property, crime, or property-crime?
Furthermore, the fox is plainly outside of human jurisdiction, as human laws bestow neither rights to the fox, nor impose duties upon it, and as such, answers only to the will Gaia.
Additionally, for something to be considered stolen, it has to be property first, and just like the african slaves can in retrospect only be considered unrightfully exploited and abused prisoners of their so called “masters”, so can geese only be considered slaves of their human “owners”, not property, and I am confident that judgement by denizens of the future will only avow my position.
Thusly, it is clear beyond the shadow of a doubt, that the fox is not in fact a thief, but a humble hunter earning its honest keep, and ensuring its own survival for another day.
