Well there is danger, as some "facts" are politically motivated.
Liberal values, tend to see things as dangerous. The dangers of GMO food (While there is so proven science to show otherwise), Chemical whatever when used in a consumer good must be bad, because if you drink it in raw form you will die...
Conservative values, tend to lead to things being safe, Global Warming is not caused by Humans, The chemicals that we pump into your water supply is safe.
Points evidence or lack of evidence is often explained as a conspiracy by their opponents to keep the truth away from us. (Sometimes this is true, smoking, lead, etc...) Other times it is just hoping it isn't the case and delaying the process until real evidence comes out.
Especially if it is rather new, much of the science is just in the hypothesis state, and probably just started recording data. There isn't facts, but a lot of opinions, worded as fact.
Now Google as an institution is left leaning. While their intentions may be good and not trying to push a political agenda, their algorithm will closely match what how their brains would match facts vs bluster, thus creating a subconscious autonomous political leaning system.
