I remember a woman I was friends with in the past. A woman whose extreme bluntness I had put up with for a long time because I was never on the receiving end of it. Every hurtful comment to or about someone else was followed by the proud assertion that "Well, I'm just being honest!". One day I heard her make hurtful and thoughtless remarks about a fellow friend and when I addressed this she shrugged and again with certain pride said "Look, that's just who I am! I say what I feel!" I remember then looking at her as though I was seeing her for the first time and physically turning away from her thinking "If this is truly 'who you are', then you really aren't someone I want to know".
I certainly respect people who are honest, straight forward, and who do say what they truly feel when necessary. There is integrity and courage in that and to stand up honestly for what you believe is commendable. Where I feel this philosophy of saying whatever you feel fails greatly is when it becomes an excuse to speak without thought or consideration for others. When they hold this quality up as though it were some great badge of honor. Too often I think that saying what you feel is an excuse to be rude. To cut someone down to size under the guise of "just being honest". I think sometimes it's also a defense mechanism, a genuine lack of true confidence that one tries to cover up by creating this identity of saying whatever one thinks all the while hoping no one notices their own deep insecurity..
I find very little to be proud of in saying exactly what you feel all of the time. I think rather that it is a mark of immaturity to not speak with consideration, discretion and kindness. There is something childish about loudly blurting out every thought you have at others expense.
I think that a truly mature and confident person says quietly and calmly those things that need to be said and addresses those thing that need to be addressed with dignity and above all, compassion for others. There are things that need to be said and values and beliefs that need to be stood up for and defended.
We need less superficiality and more honesty in our dealings with others. Honesty is something pure and enlightening and speaking with love and honesty means sometimes addressing hard things but in a compassionate and kind manner. Not throwing ones arms up in the air and saying defensively "Calm down, clam down, I was just being honest!" No chances are, you were just being hurtful. There's a big difference there. ;)
