I admire that approach, and didn't know public school teachers had that much say in the selection of material.
Some do; some don't. It depends on administrators and districts...and, to a certain extent, the guts of the teacher. This year, I have been allowed to pick all of my literature for my ninth and tenth grade classes.
About the only Christian influences I could find in my public high school was 1) a hymn we sang in school choir (though the choir teacher made it abundantly clear that she didn't believe in the sentiments of the song), and 2) reading the book of Job in Honors English. This latter was treated with as much reverence as when we covered Steinbeck's The Pearl.
That doesn't surprise me. I know that has been the experience of many. My situation is unique.
I did want to address some of the things you mentioned in your reply to aCW. First, I'm not unionized and I have yet to meet a teacher that is a member of one. I know they are out there, but I haven't met one. Moreover, no one has ever encouraged me to join one, and I won't if ever asked. Second, as to the glamorizing sin in English, what's funny is that in a number of the pieces we study gross sin shows its destructive nature. By way of example, we studied
Antigone last nine weeks, the theme of which is the devastating effect of pride. I think that lines up pretty clearly with the Christian worldview.
I'm still of the opinion that the system is overall evil in spite of wayward cogs like yourself and aCW's friend, but I'll try to wedge my mind open, if just a little.
I think in many cases the system is evil, but I love that I can work against the evil from within it. The young people I teach know who I am and what I believe, and I've had a number come to me and ask for prayer and advice. That's enough for me.
