Please don't rush forwards with the obvious answer.
For me, a Klingon is a Warrior, but that's not all. Many are born into great Houses, but surprisingly few become renown Warriors, or De'Har Masters.
My mother joSa’reH (Josa'reh) Is a Planetary Geologist, a Scientist.
My Brother qaven (Kaven) is the head of my Clan's shipyards Hull construction. design and repair facility in the Chin'toka System
My Uncle qorSh (Korsh) Spent many years as a Defence Lawyer, before taking command of a Ship again during the Dominion War.
But each considers themselves a Warrior of the Empire. My mother fights to find worlds worthy of joining the Empire, to find out which are worthy of colonising, to support our people.
Without my Brother and those like him, our ships wouldn't fly and our Disruptors wouldn't fire. (We'd stay at home, and fight each other, and that's not good,)
And with out my Uncle's legal wisdom, many times a good man would have been wrongly put to death or imprisoned, for things they hadn't done.
Like any other race, we are judged on the members of our society that you meet most often, and with Klingons, that's often our military.
But spare a thought for the Farmer who battles against nature and the seasons to bring in the Harvest,
The Doctor who battles to save lives, and fight disease.
And the Teacher who fights ignorance, with Knowledge.
Then tell me, what for you makes a Klingon?
Some still see us as Brutal and Warlike, with short tempers and argumentative personalities, always ready to fight and kill. But that's not the FULL story. . .
I sometimes wonder how an outsider must see us.
