Buying a gun is easier than buying a book? Really?
That's funny, I can walk into my local B&N, grab a book off the shelf, pay for it, and walk out again five minutes later--and it only takes that long if there's a line. I can go to Amazon, "buy with one-click," and have a book delivered to my door two days later--or have an ebook delivered to my device of choice in seconds.
In order to purchase a firearm, I have to fill out a six-page Federal form, produce ID, and undergo a background check that takes a good half hour or more of cooling my heels. And this is in Utah, where buying a gun is a relatively painless process. In places like New Jersey and California, that process is much more difficult. Fortunately, there's a lot of Shiny in gun stores to occupy my time, so that's not a particular hardship. I certainly cannot just buy one online and have it sent to my home--if I want to buy one from, say, gunbroker.com, I have to have it delivered to a licensed firearm dealer and pick it up from them, after filling out that same six-page form.
As the article linked above notes, if you're talking "more gun stores than bookstores"... Well, that too, is factually and laughably incorrect. Your hometown of Chicago proper has exactly zero gun stores, though there's a few on the outskirts of the city that serve the needs of the few people there allowed to own them. As for the rest of the country not laboring under the bootheels of control freaks, this may actually be true, but it's only because Amazon and poor business practices killed most brick-and-mortar bookstores deader than the buggy whip.
So, before you go spouting off utter nonsense that sounds good to your sycophant sheep who gobble it up without utilizing a single brain cell in the process, perhaps you ought to check your actual facts so that the rest of us don't feel like throwing things every time you open your mouth about an issue that you have a lot of Feelings about but don't actually know anything about. That'd be peachy.
