Yagecero, thank you for editing your post and for recognising how a friendly discussion could easily turn into a not-so-friendly argument! I think the bipolar debate definitely needs to end here, before it becomes too heated 
It does sound like the situation is extremely difficult for you, and as you say we can't walk in your shoes and see what it is like for you. I imagine it is all the more intense given that you live with this person. Regardless of the reason behind his behaviour and the difference of opinion about bipolar, if his behaviour is too much for you all to cope with, then that is perfectly okay - there is only so much we can handle! I think the options are either he modifies the behaviour that is causing you all distress (this may involve getting more help with coping with his illness, or changing his patterns of behaviour while in the house) or he does not continue to live with you guys (maybe he needs to be with his family where they can look after him, or conversely maybe he needs his own space - I don't know him so I don't know what would be best). Judging by how heated the discussion got in here, I think it is best to avoid bringing that side up with him, if you want to have a calm and productive discussion
Good luck resolving the situation - I hope it works out for you

Sorry that I have nothing to offer but did want to interject my thanks for bringing up lots of questions---I vastly prefer questions to answers
