If one wants to get facts about drug reactions (for example) then sure, there will be articles in reputational journals reporting on studies (that should be objective), as well as straight up reporting, like the adverse reaction data. But as soon as you want context or analysis on how to interpret the information and what to do about it, opinion and world view are involved. There may also be legitimate or groundless views about the trustworthiness of figures reported, potential cover up or under reporting, etc. This all gets magnified when it's about a topic that is being used as rhetoric to change people's behavior.
