Encyclopedias are a compendium and summary of accepted human knowledge. Their purpose is not to provide compelling and interesting articles, but to provide accurate and verifiable information. To this end, encyclopedias strive to always represent each point-of-view in a controversy with an amount of weight and credulity equal to the weight and credulity afforded to it by the best sources of information on the subject. This means that the consensus of experts in a subject will be treated as a fact, whereas theories with much less acceptance among experts, or with acceptance only among non-experts will be presented as inaccurate and untrue.

Before you even begin to try to raise the issue at a talk page, you should ask yourself "Is this article really biased, or does it accurately reflect the views of authoritative sources about this subject?" Do some research. Read the sources used by the article and find other reliable sources on the subject. Do they present the subject as controversial, or do they tend to take a side? If there's a clear controversy, what field of study would impart expertise on this, and what side do people who work in that field tend to take? Do the claims made by the article match the claims made by the sources? Depending on the answers to these questions, the article may not be biased at all.

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.
