For a test of tolerance perhaps lightly more realistic, try issues believers face almost daily:
Billy is pro life, basing his position on the belief that the human embryo is human being from conception , because it possesses a soul from that instant
Jimmy is pro choice .A secular humanist, Jimmy believes an embryo /foetus becomes a human being when it is viable ex utero. This normally considered to be six months. Jimmy does not believe in the soul, arguing that the existence of a soul has never been demonstrated. Jimmy believes an abortion is a medical decision between a woman and a doctor, not a moral issue.
Jimmy is openly gay and has a boyfriend.
Billy believes homosexuality is a perversion and mortal sin. The result being that openly gay people are not welcome at his church.
I look forward to a response of christian compassion and acceptance.
