Jihad is the most maligned term in Islam
Here is what it actually means (from wikipedia )
Jihad, sometimes spelled Jahad, Jehad or Djehad, is an Islamic term, ("to exert utmost effort, to strive, struggle"), which connotes a wide range of meanings: anything from an inward spiritual struggle to attain perfect faith to a political or military struggle to further the Islamic cause. Individuals involved in the political or military forms of jihad are often labeled with the neologism "jihadist".
The term "jihad" is often rendered in western languages and non-Islamic cultures as "holy war", but this "physical" struggle, which encompasses warfare, only makes up part of the broader meaning of the concept of jihad. The denotation is of a struggle, challenge, difficulty, or (frequently) opposed effort, made either in accomplishment or as resistance. A person who engages in any form of jihad can be called a mujahid (in plural: mujahadin) (Arabic: striver, struggler), a term even more often applied to groups who practice armed struggle in the name of Islam. He might engage in fighting as a military struggle for religious reasons, or for example, struggle to memorize the Qur'an.
Muslim scholars explained there are five kinds of jihad fi sabilillah (struggle in the cause of God) [1]:
Jihad of the heart/soul (jihad bin nafs/qalb) is an inner struggle of good against evil in the mind, through concepts such as tawhid.
Jihad by the tongue (jihad bil lisan) is a struggle of good against evil waged by writing and speech, such as in the form of dawah (proselytizing), Khutbas (sermons), and political or military propaganda.
Jihad by the pen and knowledge (jihad bil qalam/ilm) is a struggle for good against evil through scholarly study of Islam, ijtihad (legal reasoning), and through sciences (such as military and medical sciences).
Jihad by the hand (jihad bil yad) refers to a struggle of good against evil waged by actions or with one's wealth, such as going on the Hajj pilgrimage (seen as the best jihad for women), taking care of elderly parents, providing funding for jihad, political activity for furthering the cause of Islam, stopping evil by force, or espionage.
Jihad by the sword (jihad bis saif) refers to qital fi sabilillah (armed fighting in the way of God, or holy war).
