Who Pushes Off With Their Trail Leg?

Right - this is what I meant when I said at least some of the misunderstanding is semantic. If your foot is applying a force to the ground, that's pushing (in my opinion anyway), even if the leg itself is not actively doing anything to push there. To go back to the hammer and nail analogy, a nail being banged into a piece of word is pushing into the wood, even if it's really the hammer that's doing the active work.

Well that's a very loose definition of the the word "push" IMO. My butt isn't currently pushing into my chair, but a force is exerted upon my chair simply because of mass of most of my body and gravity. My phone isn't pushing against my desk. My keys are being pushed when I type, but not the ones that I'm resting my fingers on.

Your trail foot has to exert a force simply because it's supporting portion of your body weight. That's not really a push. Or to put it another way, if I ask you to lean against a wall or push against a wall, you're going to do two different things, wouldn't you? You're not going to lean against the wall and tell me, "But I'm already exerting force on this wall, that's pushing."

It's not semantics. Pushing is an active thing when used in this context.

My TV is sitting on my credenza/tv stand, but it's not really actively "pushing" on it. Gravity is doing the pushing, if anything.

No. That's not how it's used, otherwise it lacks context and becomes non-sensical. You're always pushing with both legs even when you're actively doing the opposite (adding flex to the knee/hip). So, again, no.

Yeah. Almost the same kind of examples I gave.

Good examples there too.

Imagine you are in the squat machine at the gym. If your legs are fully extended, you can't push anything. You can support the weight. You flex your knees, taking the load onto your muscles. What motion causes pushing a weight. It is the extension of the knees. 

In the golf swing, you gain flex in lead leg. Which tells that the golf swing is priming to push off with the lead leg, not the rear leg. It makes no sense that a golfer would push off with the trail leg in the golf swing.

You can "push" laterally, too, with trail leg abduction.

Studies show this is typically what bad golfers do. Brooks Koepka likely does a bit more of it than most, though, at the Tour level.

I'd call abduction a lateral push.
