My Dad punishes me all the time for little things, but he does things a lot worse! What should I do?

I'm sixteen, and am always getting punished for my attitude. Snide little comments under my breath & stuff, you know how it is. I strive for self control & I never lash out or curse, but comments like that sometime slip out, but its always very settle. One the other hand,when my Dad gets mad, he swears like an R rated movie and breaks stuff, spills coffee...that sorta thing. Yet, he's always punishing me for what I do. If I did what he did....well I'd get punished for life. The social structure of families just doesn't seem fair sometimes. He demands respect, but how can I give it to him when he acts like that?
