The only important definition is the legal one. The President doesn't make law. The ATF doesn't make law. The Constitution is very specific about how laws are passed and then they still can be overturned by the supreme court if they are not Constitutional.
.
Still the only reason I would be concerned about the ATF's definition,
Is that I am fairly certain they will be consulted by lawmakers should the question arise,
And they will be responsible for enforcing whatever law is created should the definition be required.
That's not saying it should be one way or the other,
just the ability to understand what will probably happen.
I am also not prepared to pretend that the Federal Government won't try, and hasn't already been successful ...
In regards to infringing upon our Constitutionally Protected Rights.

A large majority of Americans want universal background checks,
That's because the term "universal background check" is incredibly broad and vague. Most likely support plummets when you drill down on what that means in terms of policy. Much like abortion, universal healthcare, anti-racism, etc...
What is so complicated? You sell a gun, you do a background check, just like dealers do now. Of course, you would have to go to a dealer to do it, and it might cost 3 or 4 dollars. Do you prefer felons buying guns without even having to tell the seller their name, or even caring if the purchaser can legally have a gun?
what makes you think thats going to stop a felon from getting a gun??
It won't stop all of them any more than wearing a seat belt stops all car deaths. You can't get 100% success from any program.
The problem is crime; not guns and always has been. You want to stop crime? Everybody wants to stop crime (except criminals and the hopelessly insane) more gun laws are not the answer because:
You can't disinvent technology. Guns, and the knowledge to make them exist, are plentiful and here to stay. As far as crime is concerned that is actually a good thing because it can help even the odds between vulnerable potential victims and attackers. People never had much problem murdering each other before guns were invented and if every one of them disappeared it is doubtful that it would have much effect on murder rates. So you're stabbed to death or blown up instead of shot; is that somehow an improvement?
We had an "assault weapon ban" for ten years that had absolutely no effect except to inflate gun prices and increase sales. That ban was implemented as a trial. It received support from some gun owners because it was to settle the question of whether more restrictive gun laws would improve the situation or not. It didn't and so the question was answered. Unfortunately that hasn't stopped some of the sheep from continuing to bleet about the already settled issue. There are already laws intended stop everything the gun grabbers claim to want to stop and they can present no reasonable rationale to believe that new repressive laws will work any better. I have heard that the definition of insanity is continuing to do the same thing over and over and expecting a different outcome. You don't curb crime by creating new criminals which is exactly the risk being run. Maybe it's past time to address the actual issues instead of continuing our wheels in the same rut and creating damage instead of progress.
