I don't understand why people keep stating Silk Road did not sell guns.

Here's a thread in a forum where someone quotes Ulbricht's message stating Silk Road will no longer sell guns.

Yup. And just for some context regarding guns at the time; during the years Silk Road was active it was perfectly legal for me (in the state of Virginia) to buy a gun from another citizen cash in hand without ever showing an ID, filling out a BoS, or any paperwork whatsoever.

I saw it when it was active.
