There are some fairly major points about Gandhi's philosophy and how he developed it over the years which cannot be covered in this thread.
With all due respect, if you feel that your current position is correct and that there is nothing else to learn then by all means carry on. If you are interested in learning about Gandhi from his own words and only want to read one book, I'd recommend this one:
I guess you'd come out the other side with more or less the same beliefs since you've spent some time developing your opinion based on your research and experiences but this book will give you a better understanding of Gandhi.
I've put myself in harms way in the defense of others, including working as a peacekeeper in the Balkans. I walked through entire villages which were wiped out and the survivors displaced. I worked as a EMT at WTC. Trust me, I get your underlying message.
I have no intention of allowing myself or any other innocent person to face harm at the hands of a predator if I can do something to stop it. On the same token, violence committed in defense should always be an absolute last resort. In the case of national defense, when diplomacy has failed or imminent danger. In the case of defense of self or the innocent, the measured act is the lowest use of force on the continuum which will resolve the issue.
