Greetings of peace be unto you dear family of believers,
Indeed you are a very special set of people... I have been looking at this thread and am deeply moved by how you guys (without anyone coercing you to do this) have taken it upon yourself to learn about another despite all the negative 'press' to say the least that they have been given. This bears testimony to your intrinsic goodness and your commitment to being upright people. I can say more... but will stop for brevity.
Yes actually my name is Jihad. Jihad comes from the root جهد (jahada) which literally means to exert effort.
(See Edward Lane lexicon:

In itself, it has no moral value. One can exert effort for the good or for the bad. In Islam, took this idea and has been cultivated and developed it into a belief that a Muslim (meaning one who is surrendered or at peace with God - for the root سلم - salama) is one that is one committed to stand against evil wherever it is found; and first within themselves yet never in isolation from their surrounding. Or said differently, a Muslim is one who is committed to spreading good in the widest possible circles. So is a true Christian as is my belief.
The use of armed confrontation is a matter of last resort and should be governed by godly leadership, far from being a political game for the pursuit of power. This being said, 'jihad' in the sense of taking arms against an undeterred oppressor or tyrant (ex. Hitler) is conditionally considered a holy act of courage, so long as it is in keeping with an number of specific constraints, all of which revolve around the pursuit of proximity to God and service to humanity. This is the essence of the matter. How human beings have practiced this needs another discussion.
I want to give a note of caution. There will always be those who for whatever reason fail to see the spirit of things and they will interpret and coerce other to interpret the religious texts in a manner that befits their understanding. This does not mean that the truth is lost. It just means that we are responsible to be active travelers in our own journey to the truth. Given, that we are amongst a family of faith, we can say that we believe that if we keep journeying we always arrive closer and closer with God's help. What is more, ultimately we will converge with other spectacular individuals who have been (struggling or doing inner jihad) in order to arrive also.
