One of the approach that has helped me is not to try to respond when my parents are still angry. I will look for opportunity when they are already calm to explain myself.
Another approach is to realize that it is not a fight between me and my parents. My parents have my best interest at heart, though their approach may not be right or the best.
I also realize it is not about my right, because if I am always dragging for my right there may never be peace and love flowing in the home. If am trusting God by faith, and doing the right things God has a way of justifying me and defending my rights.
