Having grown up in the Evangelical world with an evangelical Baptist preacher father, I could not agree more with you. (And Dad was a recent convert from Catholicism, which made him even more enthusiastic about his religious beliefs, I think.)

So I grew up valuing the idea that Christians have to separate themselves from the world and live insular lives, apart from the "dirty sinners" who make up the rest of the world. I grew up valuing the idea that going out into the world was necessary in order to gain converts, but only for the purpose of saving them from their sin.

Only after I realized I was an atheist and spent some time studying religion from the outside did I realize that the values I grew up with were not the values Jesus taught.
