As per definition in wiki: In Maoist thought, "political power comes from the barrel of the gun" (one of Mao's quotes), and the peasantry can be mobilized to undertake a "people's war" of armed struggle Basically Maoist so called struggle of downtrodden against upper class is to grab more share of resources for poors and downtrodden.
Hence none of Maoist attacks are influenced by religion. Major difference between terrorism by Muslim Jehadis and Maoist is that Muslims Jehadis practise terrorism as a part of Islam teachings (to kill kafir, darul islam .. blah). Hence they are more potential threat to society.
While Maoist struggle is for power. In case they will be provided right guidance, They will leave terrorism.
But Muslim fundamentalist have to leave Islam to stop terrorism.
