The first thing wrong with this thread is that everyone keeps referring to radio control model aircraft as "Drones". By using the term "Drone" you are perpetuating the idea of an unmanned, and most likely armed aircraft which is actually called a UAV or UAS (Unmanned Aerial Vehicle/System). Yes I do believe that a licensed pilot should be required to fly a UAV since they pose a significant possible threat to air traffic and people on the ground if they are operated incorrectly.
You have two options. You can try and spend your time fighting the verbiage fight, trying to swap out the language for something better. Or you can try and reclaim the term and alter the nomenclature.
Both require considerable effort and each has it's upsides and down sides.
You can spot a similar analogy from the firearms arena with "assault weapons", this term was born entirely out of legislative means and done with an intent to scare and intimidate. Much the same as "drone".
You can use the alternative vocabulary all you want, even in interviews, it will usually be edited out by the media so while your effort up front was there, it falls flat.
I find there are better ways to spend time than worrying and arguing about what term I use to describe what. Doubly so if I can use that term to immediately get a mental connection with someone and then describe the system in a manner as to destroy the fear and misconceptions about it. Because honestly that's the real problem and you're fighting an 800lbs gorilla when it comes to language as the media will continue using that term even if you don't. Pick and choose your battles. You best bet in this battle is to get a solid legal definition, see your point #1.
As for #1 and #2, I did voice both of those concerns in my commentary letter. This is a power grab and well I just got finished with one from the ATF today.
