I don't believe it's even possible to be truly objective.
The standard dichotomy is subjective vs. objective. Being subjective is looking at an "object" from one's own (the "subject's") perspective, while being objective is looking at the same object from its perspective, independent of one's own. However, I believe that this is impossible. We can only regard things from our own perspective. Consider, how would a human objectively know the perspective of a rock? Now, that is an extreme example, but I do believe it still holds even on the level of a human trying to objectively consider the perspective of a chimpanzee.
So, I basically regard any person's claim to being "objective" as "fake."
Now, that said, the reason it's impossible is because we all have biases, whether individual or communal. While it is impossible to remove all of those biases, we can reduce them. An individual can never be objective, or even get close, but a community can get close. Collectively taken, our individual biases can be taken into account and removed from consideration when regarding something, thus reducing subjectivity. We all still have community biases, so we can never fully reach objectivity, but we can get close enough that arguing whether it's "objectively true" that Earth orbits Sun, for example, is semantic nitpicking.
