Anh Le Posted about 2 years ago Do we have an opinion about everything? If not, should we? I would say "No, we don't have to". Personally I give opinions that I have certain knowledge about. If I am unsure, I'd prefer to stay with the "no opinion" mode. I also think sometimes the relevancy between "assumption" and "opinion". Because somebody tends to give opinion when they are not fully acknowledged about some specific topic, is it just an assumption or should it be considered as an opinion?
