I agree with ILADVOCATE that anything like that needs to be brought up with a doctor or therepist. Bipolar causes a lot of things like poor judgement, irrationality, confusion, anger, delusions, paranoia, and even psychosis. It is best to deal with these problems professionally.
Emotionally and at home, I say the best thing to do is listen. Don't be forceful, but listen and pay attention to what your teen is telling you. If they are willing to start talking about something, then take is seriously. Don't just brush it off. As a teenager when I was having depression, anxiety, hypomania, and even psychosis no one would listen to me. I was suicidal and self-harming and I felt completely alone. The person I needed the most to listen, my dad, would just brush me off. It was frustrating and painful to think no one cared at all what happened to me.
So just be there, listen, and let your teen know you care. Bipolar is a life-long disorder of meds and doctors, so it is so important to know you have support at home, especially when young.
Since it might be a symptom I would say no. That doesn't mean its acceptable but the best way to approach it is as a symptom. Family therapy can be quite helpful in this regard as it provides a neutral environment to discuss what otherwise might be emotional issues that would create conflicts. Cognitive behavioral therapy can be helpful as well.
