I would like to infer the Maslowian Heirarchy of Needs:
The most basic is the physiological needs, then if that is met, there is the safety need, then the love/belong need, the esteem need, and the self-actualization need. Human beings base satisfaction if these needs are satisfied and supplemented. If a society can provide the basic support systems, then allow the possibility or chance to be 'accepted', then that person will never feel alienated. I would like to take into consideration one aspect in human resources managment which is employee appraisal managment systems, which looks at the employee's overall strengths and provisions. An employee's ability to perform juxtapoxed to employment specifications is influenced by support system within an organization, communication processes, as well as remuneration processes. Now, we can apply this in a population. If individual belongs to a minority group, but if his or her physiological, safety, love/belonging, esteem and self actualization needs are met, he or she will be satisfied. There will be no catalyst to radicalize. The problem with some western societies is that some of their minorities do not have their basic needs met, and of course, that coupled with financial and racial and religious discrimination, people living in abject poverty will eventually voice out protestations , ableit it may even be violent.
In regards to Japan, our society provides the foundations and resources that allows minorities such as muslims to not only feel welcomed in society, but are given preferential status as per policy that takes into consideration minority rights.
Best,
Yours Truly
