Whats even attractive about Christianity anyway that people want to stay in ignorance

[Child of Stardust]

Your grandfather probably deserves more credit for the attributes that made such an impression on you than any inspiration by faith.

Oh yes, I wouldn't disagree at all. I was responding to something mentioned by another poster about most Christians they met being unpleasant and that being a force that drove them out of the religion. But that isn't the case for everyone, and I was offering a counterexample. When most Christians you know are good-hearted and generous, it tends to make people who run into them view their religion in a positive light (even though, as you very insightfully stated, it usually has more to do with their own positive personality traits). When you associate positive things with Christianity, the faith, in turn, looks a more "attractive" thing to "stay" in. So that was my answer to the OP's question.
But, re: the remark I was responding to about most Christians being unpleasant, it works both ways. The stifling, dogmatic way my father raised me did a lot to drive me toward atheism. Like all revealed religions, Christianity has a lot of "thou shalts" and "thou shalt nots" that are to be unquestionably adhered to - so calling Christianity dogmatic is valid. But even if it weren't dogmatic, if most Christians I met were narrow-minded and tried to limit my imagination, curiosity, and skepticism, I would begin to form a more negative impression of Christianity.
