"Other Christians don't read the Bible/don't know its contents; trust me, I know a guy who that fits" is coming across an awful lot like a Mormon version of "I can't be against ____; I have a lot of _____ friends!"
I get it. You think actual Christians are ignorant because you've met some who are, but you don't want to just come out and say so because as a religion (not on the individual level, but at the level of the body itself, as it struggles to be accepted by others as a means of proselytizing them; see, e.g., its vacillating on being called Mormon) you're a bunch of cowards who want your cult to be both Christian and better than Christianity, and you can't achieve that without talking out both sides of your mouths. That's understandable given the Mormon presuppositions about what happened to the Church and the Bible (i.e., the 'great apostasy' fable and the idea that "many plain and precious things" that once were in the scriptures have been lost), but I would put it a different way: If someone in a Christian church does not understand or has not read a particular part of scripture, it is still better that they remain in Christianity than to leave it for Mormonism, because the chances of the Christian church informing them of what they do not know and thereby giving them a firm foundation in their own worship of God is much more likely in Christianity even if participated in passively (e.g., going to church and listening to the Bible there, even if they don't read it themselves) than in Mormonism, where they will learn Mormonism's soul-compromising doctrines and warped interpretations of the Holy Bible (and various fantasy novels appended to it, as though it needs them) in lieu of the Christian faith.
Even a low-quality meal is better than being poisoned.
