Now that sounds invalid because it "is an opinion" but the statement is not actually invalid. An opinion is a taste or statement that exists outside of the realm of definable, measurable facts, and is therefore not tied at all to validity, reality, or truth. This means that an "opinion" is often glorified "wishful thinking". People claim they have the right to opinions, but that's like claiming the right to be stupid. Okay sure, you have that right. It's just going to cause real and measurable problems.
Just because you like something (and therefore have a positive opinion on it) does not mean that it functions, does not mean it helps others, does not mean it doesn't destroy things, and ESPECIALLY does not mean that it is of good taste-- "taste" being virtually impossible to measure concretely, so I shall leave explaining it out of this paragraph.
An opinion always counters honesty, education, and taste in the name of fantasy and emotions. When everyone thinks and communicates with other people with no inserted opinions, life gets a lot more functional and people are happier. Opinions are for idiots-- for people who want to justify any or all things that are less than ideal.
Bob: That was an opinion, moron.
Dick: So if I say "the sky is blue", is that an opinion?
Bob: Well duh.
Dick: Well, under that logic, you can't disprove my "opinion" that opinions are stupid, so what the fuck is your point? Mine is that "opinions are stupid" is still a valid and theoretically-functional statement.
Bob. Fuck off.
Opinion: "The USA is a country full of ignorant, fat rich bastards who exploit poorer countries so that they can munch more burgers and get even fatter"
Non-Retard: Dude, a dictionary is a collection of DEFINITIONS, not OPINIONS.
