Isolation reinforces the influence of radical thinking by allowing serious and or persuasive members of the group to disproportionately define the body's agenda. When an individual only has access to one in-group social environment, that group gains a totalizing influence over the individual—disapproval would be tantamount to social death, personal isolation, and often a lack of access to the basic services that mutual aid communities fulfill. As an isolated minority, Islamic groups in the West are especially vulnerable to this form of radicalization. Being cut off from society at large through language barriers, cultural difference, and occasionally discriminatory treatment, Muslim communities become more vulnerable to additional pathways of radicalization.
