Forceful But Impartial

I've never been accused of not Speaking my mind, Though my intent has never Been to berate; Often from my tone, others Think me unkind, Because often it's been said I intimidate; I'm often like a teapot letting Off some steam, And others may not embrace Things I've said; I'll never bottle things up until I Need to scream, Nor be forced into things for which I have dread; I've heard it said of me, "You may not like the things he says, but you have to like the fact that he'll tell you to your face"
