Even worse is the perpetuation of the myth that guns can be bought online without a NICS check. The only way to legally buy a gun online is to conduct a subsequent face-to-face personal sale and transfer, or to have it shipped to an FFL who does the paperwork and submits the NICS check (unless a valid LTC is presented, but all paperwork is still completed and filed).
If I agree to sell you a firearm on the forum, for example, it is not an online gun sale. All we do is communicate online. I have to either meet you face-to-face to conduct the personal sales transaction, or I ship the gun to the FFL of your choice. You can pay me with an online, digital payment method, but you cannot take possession of the firearm unless it's a personal face-to-face exchange or through a federally licensed dealer whose responsibility is to follow all applicable laws in transferring the firearm to you.
Reading almost anything in the media about this stuff leaves the uninformed thinking that all they have to do go online, enter a credit card number, and UPS will deliver a gun right to your door. If we polled people who consider themselves to be democrats, I'll bet 90% of them would think that's exactly what an "online gun sale" means.
