the homelier trailer trash in black was justified; the altercation had all the trappings of a consensual engagement and neither party was at fault initially. however, the other trailer trash blatantly refused to vacate the aforementioned trailer trash's property after being firmly demanding multiple times. this is a violation of the non-aggression principle, and force was required to secure her property rights.
That is incorrect. While being in the right initially despite complaining about getting hit in the face, the more homely(native) trailer trash was put into a position of pursuit of the other combatant trash. The native then had the right to dare the cowardly trailer trash to vacate the property or resume the duel. However the native trash got bumboozled into carrying out a threat of using a projectile weapon(a my old friend rifle) to make the cowardly trailer trash vacate the property. Even before revealing that it was not a lethal weapon the native trailer trash lost the battle on a mental level(possibly due to head trauma).
Either recognizing this or succumbing to a delusion of fear, she then rendered the other trailer trash's head traumatized.
If we take a detailed look into how the blunt instrument(also known as shovel for those who dont do servant work) impacted the other trailer trash's skull, we can ascertain that there is a very high possibility of permanent damage to her cerebellum. This however should not, and did not in the footage, affect her ability to learn. Or in other words, her learning ability is still nonexistent.
By attempting to use potentially lethal force after informing the other duelist of her intention to use a non-lethal BB gun, the native trailer trash has commited a tresspass against trickery in honorable duel and should be penalised for it.
