Please cite the scientific research you allude to.
Read the OP.
I did. I see no mention of scientific research. I see opinions in articles and books.
The point is it’s a controversial subject and there is no definitive evidence one way or another. For every citation you provide that shows religion is not a contributing factor, I can provide equally reasonable citations that show it is.
“According to Juergensmeyer, religious terrorism consists of acts that terrify, the definition of which is provided by the witnesses - the ones terrified - and not by the party committing the act; accompanied by either a religious motivation, justification, organization, or world view. Religion is sometimes used in combination with other factors, and sometimes as the primary motivation. Religious Terrorism is intimately connected to current forces of geopolitics.
“Bruce Hoffman has characterized modern religious terrorism as having three traits:
“The perpetrators must use religious scriptures to justify or explain their violent acts or to gain recruits.
Clerical figures must be involved in leadership roles.
Perpetrators use apocalyptic images of destruction to justify the acts.“5

What if Bruce Hoffman is wrong? The traits he puts forward were not found among the angry Muslims Atran interviewed for the book.
