Hey, no matter what, things will be tough on you with immediate family blind that they are in a dangerous mind control cult. You will have to pick some battles here and there to stand up for yourself. Otherwise, you will shock your family later when you become inactive. Better to let them see you using your mind properly to question some of it.
I wouldn't recommend debating at the hall and I would not think you should always debate. But personal and family study time is proper now and again.
The worst they can do to you is assign you to a Bible study and take away your birthday and not help you go to college. But they do that anyway.
