They hate the Salvation Army for the same reasons they hate conservative women and/or minorities. They don't follow the liberal narrative - that 'Rethugs' are a bunch of wealthy, white male 1%ers who are getting richer off the backs of the poor and downtrodden, or a bunch of white, racist, NASCAR lovin' , beer-swillin' , uneducated rednecks..
Conservative people who don't fit that description must be destroyed, as well as organizations with conservative ideals.
