“When the law protects multiple attackers inflicting great bodily harm on the victims property, then there is no choice but to go outside the law.”
There was no great bodily harm being done, only words. A fist fight fight does not constitute ‘great bodily harm’.
The law in most places protects against anyone inflicting great bodily harm. The law does not protect against murder, nor does morality.
Four on one on one’s own property isn’t a fistfight.
