The conspiracy theories I have heard:
- Gargamel is a priest, the smurfs are prosecuted by the church
- Papa smurf wears red and has a beard because of ideological reasons, the smurfs political and economic system resembles communism
- Smurfs represent the seven deadly sins/seven capital vices
Lust: Enamored smurf
Gluttony: Baker smurf
Avarice: Greedy smurf
Sloth: Lazy smurf
Wrath: Grouchy smurf
Envy: Brainy smurf
Pride: Vanity smurfSMURF - Socialist Men Under Red Father
Much harder to do with the original name in French (schtroumpf).
