The idea of extending the concept of the LARP to experience real world, difficult scenarios is remarkable. Media/political polarization is a real problem today. Applying the concept of real world workshops to bridge party lines is out there today [0], but maybe tackling difficult concepts head-on isn't the best method. For some subjects (abortion, gay conversion therapy as in the article) stepping out of your own shoes into another via imagination or fantasy would tackle it well.
