Understand your own prejudice, bias and stereotypes, those of your audience and of whomever you are seeking for information. All sources have bias, regardless of how they may present themselves. The very process of selecting which information to show, say, write or present involves making decisions that involve bias, often unintended.
I encourage you to always seek out views that do not fit in with your own and give them a fair hearing. In the end your decision, your thoughts and your actions are still your own.
