Family Issues: Is a wife submitting to the husband as the head of the household sexist and outdated or simply interpreted wrong? Will a rebellious child always turn out okay if you teach them right? Etc.
Qualities of God: Is God love? Is a thousand years literally like a day? Is God present wherever two or more are gathered? Etc.
Issues of homosexuality: Was the sin of Sodom and Gomorrah a matter of hospitality not homosexuality? Did Jesus not mention it because it's okay? When the Bible seems to condemn it isn't it really talking about issues of monogamy not homosexuality? Etc.
