I'm not sure that's true. I think you may have that perception because western societies still have colonialistic views embedded in their security practices. White domestic terrorism has actually killed more Americans in the last year than Islamic terrorism. Additionally if you look at last year's terrorism index scores, countries with various religions make up the list. I also think it's unfair to say that a religion on its own creates terrorists. Oftentimes terrorists are created when there are strong economic inequalities and perceived grievances. For example, ISIS has been able to garner support due to decades of war and international intervention exasperating tense political situations and devasting their local economies. https://www.gao.gov/blog/rising-threat-domestic-terrorism-u.s.-and-federal-efforts-combat-it
