I fence live steel for the same reason I write poetry and play classical piano.
Because it's something I enjoy.
I carry a knife because the Boy Scouts and a lifetime of experience taught me that it is good to always have certain tools close to hand, one of which is a knife. I also carry a lighter but I don't smoke.
OKG, It seems to me that you are dealing with a lot of preconceived notions of what other people are all about, and having read many of your posts, this attitude kind of surprises me.
You make an issue of whether this thread would have this many hits if it were about butter knives, but that's just railing against human nature.
We as a species are morbidly fascinated by the prospect of our own demise, and therefor are fascinated by the violence which ends human life.
Why is it that no one is interested in a living history group that portrays life in rural Kansas, circa 1934?
Because it's BORING!
The essence of human endeavor is CONFLICT.
Anyone who's ever taken Creative Writing 101 knows that the cornerstone of any story plot is conflict. Without conflict, there is no plot, and therefor no story.
The human mind is geared to deal with conflict and it is by rising to the challenge and winning over that conflict that mankind rises to higher levels, be they spiritual, physical, financial, emotional or purely mental.
Without conflict all is stasis and there can be no growth or change, and by extension, no life, because that which does not grow does not live.
What greater manifestation of conflict can there ever be than warfare, and what more benign expression and outlet for that conflict can there be than a bloodless sport, training for a war that will never come, or better yet, came centuries ago, and is nothing but a historical footnote so insignificant that no high school senior will ever read about it in a school textbook?
I just don't think you're being realistic or reasonable when you take exception to the concept of people spending their leisure time learning the ways of an archaic and obsolete fighting system.
Yes, that's what dueling IS.
It's obsolete, archaic and rather innocent in these days of Nuclear/Chemical/Biological warfare.
Do I practice my swordsmanship in the belief that I'll one day have to use it to defend myself and my family?
God no! I'm a modern man, and if I'm FORCED to defend myself or my family I'll use a modern and much more effective weapon. (Like a nice modern firearm!)

I cut it, and I cut it, and it's STILL too short!
