Touchdown! Greaser!
Inexperienced student arguing with instructor, what a combo!
I've had instructors that were wrong more than once. It doesn't sound like this one is wrong though.
Yup, you have to trust your instructor implicitly, especially during primary training. As a primary student, arguing with one who is telling you that you need to pull power on short final is stupid. It is stupid for a couple reasons. First is the instructor is most likely absolutely correct. Second is the instructor is the one who will determine when you are ready to solo, if in his judgement you are not landing properly, no solo. Third, as a primary student, you don't know what you don't know.
That said, I've had instructors who were wrong too. In one case, I'd go with different instructors occasionally during my IR training. I was on a VOR approach, that basically came in perpendicular to the runway, circle to land. I'm under the hood, it was barely a vfr day but we had plenty of vis and were well below the ceiling. I had dme, watching the approach, at about 2 1/2 miles from the airport, the instructor tells me to pull off my hood. I thought it was way too soon, but whatever, I pull it off. The instructor says "look down, you are flying over the runway". Confused, I looked down and saw a snow covered corn field. So I said, "that's a corn field, I'm not landing there, we are still 2 miles from the runway". They do occasionally screw up, but a primary student should just listen and do.
