Jihadists movements are not only involved in terrorism and violence. They are also deeply involved in propaganda and meme warfare including here on Facebook. Sure some of this propaganda is aimed at recruitment of those sympathetic to their cause, but much of it is aimed at confusing, demoralizing, and manipulating those who oppose them.
Terrorism is never merely about violence. It is by definition a political act and an act of propaganda and is often accompanied by cultural messages meant to go viral to manipulate the victims and the general public into reacting or not reacting in certain ways.
Always be suspicious of any message trying to prevent “the West”, “the Muslim world”, “the Third World”, et cetera from uniting against these jihadist movements. An injury to one is an injury to all and all of humanity should unite and destroy Islamic State.
