Wikipedia's neutral point of view policy requires us to report the bad (negative) with the good (positive), and the neither-bad-nor-good, in rough proportion to what's said in reliable sources, which in this case are largely major news outlets. This is one of the five pillars of Wikipedia—a group of fundamental principles central to the function of this website. Since reliable sources are widely critical of Trump, this article reflects that. Wikipedia policy is not established at individual articles. If you think that a policy should be changed, you could try Wikipedia:Village pump (policy), although you are unlikely to be taken very seriously there without a substantial history of Wikipedia editing.
