The goal of Wikipedia has always been to summarize what mainstream secondary sources say, not what is "true" or "right" according to your or some other editor's personal opinion. See WP:DUE, WP:VNT and WP:RGW

It literally styles itself as an encyclopedia, not a collection of summaries by "mainstream secondary sources".

> Wikipedia combines many features of general and specialized encyclopedias, almanacs, and gazetteers. Wikipedia is not a soapbox, an advertising platform, a social network, a vanity press, an experiment in anarchy or democracy, an indiscriminate collection of information, nor a web directory. It is not a dictionary, a newspaper, an instruction manual, nor a collection of source documents or media files, although some of its fellow Wikimedia projects are.
