Those who pound their guns into plows will plow for those who don't.
This is essentially the same point made by Holliday:
History has a tendency of showing that the armed will enslave and/or kill the unarmed. I don't think we yet have the technology for perfect defense from this. And pretending it can't happen in the modern world is simply wishful thinking.
But yours is more pithy. Either way, it is the strongest argument for the right to bear arms.
I'd like to understand that point of view a bit better since it's alien to me. Are people who believe this to be true concerned with some other citizen enslaving/stealing from them, or their own government or some other government doing the same? If the latter case why is it thought the armed forces can't do their job? If one of the first two, what makes you think it's likely to happen? Does anyone know the probability of a western developed nation falling?
I'm not being facetious. I'd like to be able to compare the combined probability of
1. a government without hostile neighbours enslaving the inhabitants of their own or another developed nation
2. a citizen of a developed nation being killed when owning a gun might have saved him
with
1. surviving to old age without ever having owned a gun, in a developed nation.
If the first two are exceedingly remote compared to the second, then I would tend to consider them to be in the same category as plane crashes - possible, but we don't factor them in to our everyday lives. In which case the "strongest argument for the right to bear arms" would be a pretty poor kind of argument based on the fear of the improbable occurring.
The the former two are more likely than the latter, then I think
that fact would be the strongest argument for the right to bear arms.
