Fighting for your home made more logical sense when the consequence of losing your home meant you most likely had nowhere to go and either were stuck under brutal occupation or left to wander for a place to live with a high risk of dying before finding anything. With how much more accessible distant travel is these days, I can’t imagine any piece of land worth dying for, especially when considering the typical lack of support that veterans get when the fighting is over.
I respect those with the courage to fight for defense, but I wouldn’t look down upon anyone who left.
