No. This is just retarded. A lot of hands are profitable to complete the small blind with. A lot of hands are profitable to call with preflop. A lot of hands are profitable to limp behind with preflop, some even profitable (although very unbalancing and maybe not the most profitable) to open limp with. To stick to the "pump it or dump it" mantra is just an easy scapegoat for not wanting to think in the moment and consider the situation at hand.
