Truth is grey, not black and white. What we believe to be true can change over time. There is an inscription above a door at the German Naval Officers School in Kiel that reads:
Say not ‘this is the truth’ but ‘so it seems to me to be as I now see things I think I see’
There will always be someone who believes the opposite to what you know to be true. Don’t let this stop you from writing what you believe. Truth is strongest when time is spent to investigate, explain and verify the facts. The problem is that sometimes it is easier to come to a conclusion by distorting, hiding and twisting facts.
So what to do? Be honest. Don't pull your punches. Don't worry about being blunt. Tell us the truth as you know it.
