It's because as you have said they DEMAND respect. They are deadly just by them selves able to go off if dropped or in my friends case looked at funny. They are just a piece of soulless machinery able to do damage no matter the handler, quality of the gun or state it is in. Blades on the other hand have souls and personalities in many cases. They don't demand their respect but earn it. Blademanship is a work of art what you put into it you get out. I'm sure plenty of you have heard of the whole swords and energy bit where and old tattered sword that a swordsman pours all of his energy into will hold up and beat a brand new sword that was just picked up (and both swordsmen are of equal skill and whatnot). I know I'm just blabbing on and most of you think I'm nuts or something and to be honest I'm not doing the greatest at expressing myself but I guess what I'm saying is blades require a certain finesse guns. Also guns are very impersonal "bang bang he's dead" that's all it amounts to you feel nothing. With a blade on the other hand you feel every cut and slice run through you as if you were doing it with an actual part of your body. You feel them die , you breathe their last breath and what's left of them leaves through you. I know it's very morbid and whatnot and no I haven't killed any one or hurt any one with a knife (well with the exception of the time I was jumped but that's self defence). I do a lot of hunting and trapping so I've taken an animals life with both kinds of weapons and a gun is very impersonal, very numb if I might say.
