LOL. I didn't mean to go into macho/control areas, but that was good. Anyway I prefer that the person going forward supply the drive, for several reasons.
First, to me, the human body has more translational power in a forward sense. Sprinters sprint forwards, baseball players turn around and run forwards on deep fly balls, basketball players aren't supposed to backpedal, but rather turn around and run down the court. So I really can't agree with you there, until I see sprinters backpedaling across the finish line. From a dance perspective, I find it awfully difficult to maintain a forward poise (in either Standard or Latin) and move backwards with any stride. This means that if
I'm backing into a weave, or a backwards rumba walk, I have to be able to count on the follow to supply the drive, and I have to be able to absorb that energy and use it to open my stride. That doesn't mean that I supply no power, but that my ability to supply power with that shaping is limited. And in my experience, even relatively slight women have the capacity to drive me backwards (I weigh 180-185 lbs,) so I doubt it's a problem for some of the powerhouses one sees on the competition floor.
Second, it's hard to keep your centers joined if the person backing up pulls away. It usually creates a slinky effect, where there's suddenly a lot of "daylight" between middles, then suddenly they close again. Now for Smooth, that's maybe not such a big deal, I don't know, but for Standard that's not so good.
Third, and this is more subtle, but if I try to pull the lady, generally I arrive over my back foot too quickly, and my hip sort of pops back. That creates a somewhat ungainly stop to the motion, rather than the flowing appearance usually desired in the swing dances.
Of course, this ignores the power dynamic of turns, which is totally different.
Anyway this is not to say that I think there is no value to the new approach. Certainly, if I go to a local studio party, I often have no choice but to pull the follow, as social dancers rarely have the instincts to drive aggressively forward (probably because most leads would complain vociferously if they did.) And I realize that perhaps one could apply this model to higher levels, but IMO that just means the lead isn't supplying enough forward drive and isn't sensitive enough to the forward drive of the follow in the backing position. So basically it's the guy's fault
