A drag race does not necessarily have a drag queen at the event. Also the sticklers for ''kerect'' aerodynamic terninology don't all agree on what is parasitic or induced or transitory.
I remain steadfastly attached, thu a semantic layer, to the belief that drag n lift are the same thing - If it helps do a job that needs to be done - I christen it lift -If it gets in the way - it becomes drag.
Keeps life simple and easy to negotiate.
You may have a group of sticklers in mind who don't agree on the definitions of different components of drag, but they are unambiguously defined. That some people get it wrong doesn't change that.
I seem to recall that you have, in the past, cited some useful functions of drag. This would seem to be inconsistent with your statement here. How about this: you need your plane to either slow down or lose altitude without speeding up excessively, in order to land. Do you now claim that the force that I would call "drag" has just become "lift", simply because it is doing something that you want?
Drag and lift are unambiguously defined, and they are not the same. You can remain steadfastly attached to a different view, and you will simply be contrarian and incorrect. This is fine until someone earnestly asks a question about aerodynamics and you give them a faulty answer. I find that to be unhelpful at best, and just plain silly.
