-- Well this hits home with me. I was raised Christian and once I got older, I realized it wasn't the right religion for me. At one point I had to move back in with my parents while I searched for my own apartment. Those few months were an absolute nightmare for me. Even though I wasn't any other religion at the time, I didn't identify as THEIR religion and every single waking moment they guilt tripped me and shamed me for it. Finally, they said "while you're under our roof, you'll be what we say you are". 

-- I said "fine" and left the next day. I moved in with my boyfriend (whom I'd only been dating for a week). My mom cried when she found out I wasn't coming home and is still extremely broken up that I "shacked up" with a man whom I wasn't married to. But they're the ones who made that rule and I followed it by leaving. 

-- So my question to those who would place this rule on their kids is: if your child (any age - 10 years old, 15 years old, 18 years old ect) were to decide they didn't want to believe what you believe, would you kick them out? Because you're giving them an ultimatum; lie and submit to me, or go live out on the streets (if they're LUCKY they'd find a friend or SO to live with). Is that really ok with you??
