"An imminent threat of fatal bodily injury is not necessary for something to be self defense, you moron. How about I kick you in the nuts over and over again for about an hour. That's not fatal."
Depends on the state. In California, for example, that would be justified homicide ("great bodily injury.") On the other hand, in Texas, it would not:
" A person is justified in using force, but not deadly force, against another when and to the degree he reasonably believes the force is immediately necessary to prevent the other from committing suicide or inflicting serious bodily injury to himself."
(See also Texas Penal Code, Title 2, Chapter 9, Section 9.32, "Deadly force in defense of person.")
Of course, unless the state has a stand-your-ground law, there would be a duty to retreat instead of using deadly force, in any case, although if you failed to do so before being kicked in the nuts, I imagine you could raise a good argument that you couldn't thereafter.
"Also, homophobe violence against gays happens on a daily basis so you're either an ignorant fuck or an apologist for sexual orientation based violence."
It does, but rarely rising to a standard allowing killing in self-defense. And still, given your very broad use of "homophobe," most homophobes do not injure gays physically. In your first post that I responded to, you said, "If the gays were to pick up arms and start putting homophobes like yourself down then you'd be okay with that."
It's clear you were talking about vendetta killing, not self defense; and you certainly have not a shred of evidence that gunfighter has ever physically harmed a gay in his life; so stop trying to get all technical now and pretend you were talking about justifiable homicide. You were just spewing fallacy because you thought nobody would call you on it.
You were wrong. As usual.
