Being true (or in other words – Hate me now)

I don’t know if it is me, or my condition, but I have noted that the more I avoid getting into arguments, the more I get negative energy directed my way.
I mean, if my truths (or opinions) are not subject to anyone’s approval. Why does it hurt you (or irritate you), if I choose not to have any opinion about yours?!
And by the way, I never claimed to be an expert on the field.
