I don't think that there is a big difference between facts and opinions. Opinions are something that you have grown up believing and based on your beliefs you take the facts and then state your opinion based on what you belive. Facts are what you find during your research on certain subjects. When one finds facts I guess they all bring the personal opinion into their findings. So when you use facts I think that you need to be careful about what you belive, because everybody's facts are mixed with their opinions.
