I don't know why everyone wants to call the flop; because you got 3bet?

In a small pot, Hero makes money by inducing postflop errors, not protecting his share of the pot.
--> Villain left to act is likely to make an error by peeling
--> When hero is behind, he's making a substantial error by raising
--> When hero is ahead, villain is less inclined to call down with a weak hand
