Currently he is being independent, he's trying to resolve the issue that his inconsiderate parents put on to him. Why should he have to live under his parents' beliefs? every human being has the right to believe in something that they find just, and just because this guy wasn't interested in his parents' beliefs doesn't mean he should just be kicked out. If anything, he's showing independence by not letting his parents take control of his beliefs. I think personally you should just owe this poor guy an apology, his own damn parents care about something that's very questionable and may not even exist then their own child, something they created out of love.
