You shouldn’t have to read a book and report on it if it violates your faith. The teacher probably doesn’t understand that the book is biased, since many non-Catholics simply accept such information as plainly factual–if the teacher is non-Catholic, that is.
You can do a couple of things here. You can read the book and point out in your report how it is biased. Or you can tell the teacher that it would violate your conscience to read it, so you’d like another book to read and report on instead.
If the teacher won’t budge regarding what book you are to read, again you have some options. You can read it under protest or you can complain to the appropriate school authorities. But let’s hope it doesn’t come to that.
As for academic dishonesty for getting replies on CAF, no, that’s not academically dishonest. It’s called research. If you do decide to read the book, etc., you can mention that you did independent research on those things that are biased in the book, if asked, but you do not need to volunteer your sources. Especially if the teacher is so biased s/he’d demote your grade for researching your own fellow believers’ knowledge.
