What? Me worry?
In theory that can't be right.
In theory TRUTH means CORRECT
2 + 2 = 4 is correct no matter what you might argue (we are in base 10 here before anyone tells me otherwise) but in the Trump and Brexit era the phrase Alternative Truth seems to have emerged.
There is a difference between "truth" and "fact". Truth is what someone surmises from all the information available (and how that information can be understood); whereas fact is something that is provable and repeatable without change. A perfect example (seeing how you politicized it) is that for many the truth is that Trump colluded with the Russians. However, this is not provable so it is not a fact. Everyone has to find their own truth.
