the opposite of a fact; an opinion is Someone's personal judgement on something. Things like quality of TV shows, movies, books, people, bands, etc etc are all opinions. Stupid people often believe that their opinion is a fact and that everyone who disagrees with them is a moron. (I.e. Everyone who is involved in politics) opinions are, by their very nature, not factual, nor false. Things like tv shows movies, books, etc are all subjective mediums, which means their quality differs from person to person based on their opinions.
An opinion would be " George Bush is stupid" or "anime is for kids". A fact would be "George Bush is a human male and former president of the USA" or "anime is a type of animated tv show".
That one thing everyone has, but no-one will give enough of a fuck to acknowledge in debates/heated arguments.

The personal views and ideals of any particular human being (animals may very well have opinions as well, but I'll never know) that are generally revealed to others as a form of self expression. But can also be kept to oneself as not to be offensive or abtrusive.
Opinions are usually wasted if no one know's who you are. But unprecidented and moving displays of wisdomwill never be overlooked. Think about that carefully.
