I would say double standards and bias is a problem that is tied in with prejudice that deserve equal attention because things double standards and bias in my opinion reinforces prejudice attitudes. Another thing is that many of worlds problems aren't black and white or right vs wrong and good vs evil. In just about every conflict people on both sides believe they are right and what they fight for is good, yet often in these debates both sides will have some good reasons and some bad reasons to support them.
