I think the real problem here is the ability for anyone, particularly a dwarf to wrestle a bear to death.
Haven't you ever wrestled a bear to death?
That does remind me of a thread on some random forum once. A guy was determined to kill a grizzly with nothing but a combat knife. His reasoning was that he could charge straight up to the bear, but it's throat, then get away, while the bear would be too confused to attack (?). I doubt he ever did it, seems the insane ramblings of a madman or the boasts of an idiot looking for attention.
Personally, if I ever went after a bear, I'd want a Browning Automatic Rifle (the one developed at the end of WWI)... and an armored personnel carrier.
In the context of DF, there should be little reason to have genders affect skills or capabilities. These are DWARVES, not humans, and human reasonings have no place in determining anything about our favorite, hairy psychopaths. I would like an easier way to determine them at a glance, which would just mean introducing gender into the nouns and names of the Dwarven language. At worst, having different pallets for the male/females, but that isn't even needed.
