I'm sorry, but if you are going to take things that way, then I cannot help you.
I never said anyone is a liar.
People can get things slightly wrong, and that is a fact.
People can intentionally twist the truth, and that is a fact.
Yes, I would be more prone to believe someone who has been there.
That does not mean you can take it as the gospel truth every time without checking validity.
I understand that people have personal feelings, but if you are going to inject personal feelings into your collection of data, then your data may become tainted. This is part of what is wrong with the world today.
It is also why propaganda works! If you let your personal feelings control what you believe, then you are potentially setting yourself up for loss.
And heaven forbid someone actually speaks out and says something controversial... oh my, we can't have that, can we.
