I'm not sure if this is a general reply to the thread, or to me, but here are some thoughts anyway:
Swords are usually bought with display or ceremonial purposes in mind. While this is true of a lot of guns, very few people are observed buying swords for the purposes of self defence, or for training every day at the range so that they can defend their families "come the revolution".
In short, there is no sword crisis. There's very little kudos or street cred afforded to people who drive around with a rapier in the glove-box.
I'm not sure this discussion is really about fear, but if you don't fear someone who has the point of a broadsword pressed against your chest you may have issues (less pressing than the one near your heart, admittedly)
Overall, I'd say that the issue of swords is not an argument for preventing the banning of guns. It's more an argument for banning swords as well.
