Smurfette was an anti-feminist plot. All of the other smurfs had talents or interests. Hers was being a housewife and batting her eyelashes. And when baby smurf was discovered under a cabbage leaf, she took care of it.

Also, the plot where she was created evil, then captured by the other smurfs and kept in a cage until they could forcibly give her an organ transplant. then she was magically tamed and became aryan. I think smurfette shows that the smurfs are actually a Nazi plot.
 

They're Belge. 'nuff said. Sheesh.
