Language is subjective...so if you mean something different by 'truth' than others..(and different from most formal, logical, scientific uses), then you get subjective answers.

Truth, as in 'fact' should not be subjective, but when you get to issues like "what's the truth about Mel Gibson's state of mind?", it gets REAL hard to decide. The word should be avoided in cases like that, but it's just too popular...
