I disagree that they are exactly the same thing. A book is not a firearm and a firearm is not a book. If they were trying to collect every copy of the constitution and burn them in order to eliminate all traces of the 2A, then yes I would have a problem with that in the exact same way I would have a problem with a book burning. I completely agree that more people have died due to religious beliefs than firearms (the crusades being the most heinous example of that), but books and religious speech are a 1st amendment issue, not a 2nd.
All I'm saying is that I don't see the problem with people doing whatever it is that they want with their own property. Would you tell someone they can't sell their classic car that needs to be restored to have any real value to the junk yard for scrap? I think that's a much closer analogy than a book burning. If you think people are stupid for participating, that's one thing. But if you don't think they should be able to do what they want with their own property, then that's something entirely different.
