The brother should have focused on the girl's beliefs and assessing why she came to believe what she believes. Looks like Chacha went on his normal talk without taking context of the conversion into consideration. She seems someone willing to listen and respectful and would be nice if he disected her belief and her background more.
He never listened what she told him. She's not a Christian... The Uncle shouldn't talk about Slavery because there's no Point like he said Arab had and still have black Slaves...
