Conceding the point on the rareness of bibles before printing presses (which came about in 1444, and the Protestant Reformation happened within a century, imagine that.)
However, explain if you would, how it could be I could get through 12 years of Catholic Education and never have heard of Jephthah? In fact, the only character in the Book of Judges (which is one of the most fun books in the Bible, really) that we got a bowlderized version of was Samson and how he brought down a temple after his hair grew back.
As for Genesis 19, there was a solid discussion of that book in my Freshman year, not in religion class, but in literature class. This Christian Brother (who wasn't just gay, he was FLAMING) had a textbook that ends with Mrs. Lot getting turned into Salt. (They leave out the drunken Hillbilly Sex.) Teenage boys being what we were, needled him on whether it was the gay stuff that made God kill them all. We really didn't have a in depth discussion about how Lot could be a "righteous" man offering his daughters up for gang rape.
There you go Dr. Drock, disrespect. If you want to discuss the matter in a mature and relevent way, then you don't say things to disrespect those who hold the text sacred. It's really that simple, there's no need for that unless your goal is to harass and belittle those who take it seriously.
Still seems to me he's just giving a different opinion on the text than you have.
If he's bashing you for having a diff opinion than him than that's different, but i don't see that in this post.
