What are they really?

I mean.. if you think about it, Smurfs must reproduce by budding or fision. They were an all male race, and the one girl was made by the guy that wanted them all dead.. So.. if thye're not reproducing that way, they must be like insects, with one queen.

What does "I smurfed her" mean?

And are the smurfs communists? They wear all white, and the leader wears red. The only smurf that thinks differently is shunned and hated by most of the others because he's not conforming.
