Well, exactly how old are you; what other dynamics are going on here? If you are still a "kid at home", especially if it is still your first stint at home (from birth to 18 years) you just have to do what they want, I imagine. I think the religious analogy is a good one however. To me the ethics of it would hinge on whether you are paying rent. If you are paying rent, then I would consider the room you are leasing to be "yours" during that timeframe, and ethically I believe you should be able to do with it what you please during that time, especially if you have no specific agreement, verbal or otherwise, forbidding certain legal behaviors. Legally may be a different story. If you are not paying rent, then they are strictly doing you a favor, and you should suck it up and respect their wishes completely.
