Can lack of knowledge affect you decision making? Even opinions?

When we were discussing Habibi in class last week I definitely supported the argument about bashing the Jews. I was totally stuck to that thought until I came to class the next day. My group gave me a different outlook on the issue. Some of them educated me on the issue between Jews and Palestinians. I found it to be very interesting. I had no idea the horrible things the Palestinians and Arabs went through. After receiving this information I changed my opinion about the book. I no longer thought of the book as bashing Jews. I am not sure how I exactly feel about this piece of literature. I know for sure that I would put this in my classroom because I am not as confident with introducing the book to my class, but the book is not as negative as I first thought.

Overall I have found when reading literature I always have to realize there are two sides to a story. Along with that if I am not as educated on the issue I am reading about, it is not fair to make strong judgements without knowing the true story behind the book.
