Would it ever be an option to take up personal arms to fight a tyrant ruler who gains control... ?
The answer is yes, but it is an extreme situation when people actually do it. I'd venture to say it would take quite a bit for me to risk absolutely everything. And I'd exhaust all other options before I'd be willing to resort to armed resistance. I have a lot to lose before I'd be willing to take up arms in a conflict with a very uncertain outcome. Sadly, people have always been forced to do it from time to time, and people are doing it right now as I sit comfortably typing this.
I think people are already suffering under tyrants in this country. We call these tyrants street gangs. They claim rule over territories and control certain economic activities. They use violence to control the population in their territories. Have people taken up arms to throw off that yoke? In some instances, yes, but often only to replace it with another even more violent gang/ tyranical ruler.
Not to quibble, but the government does not give us the right to bear arms; it is an inalienable right reserved by and enshrined in the 2A.
Good luck with your schoolwork!
