The word opinion by the dictionary means "a view or judgment formed about something, not necessarily based on fact or knowledge." -The Dictionary. Its synonyms include the word belief which is exclusively always a matter of preference and has absolutely nothing to do with logic, proof or an argument.
I think you need to get a new dictionary. "Belief" is certainly not always a matter of preference nor is it something that has nothing to do with logic, proof, or argument (opinions are not, either). Beliefs are views that we hold, or rather, statements we assume to be true. In the case of empirical beliefs, they may actually turn out to be true or false depending on the state of the external world and how well my belief corresponds to that.
For instance, I
believe
that the earth is round and generally spherical. It also turns out that it happens to be a matter of fact that the world is spherical, given overwhelming observations and models that cohere with and correspond to this fact. In this case, my belief that the earth is spherical is a belief that is both justified (strong reasons for believing it) and true (corresponds with the external reality). When we speak of knowledge, epistemologists often point to something like Justified True Beliefs (J.T.B.s) as counting as knowledge, see for instance: The Gettier Problem. I also believe that right now my X-Wing collection is at my house in a Plano case in the basement. I'm certainly justified in this belief (I have no reason to think otherwise, and it's the inference to the best explanation), but whether it is true or not depends on the state of the world at this very moment. So do I
know
that my X-Wing collection is home in its Plano? Maybe my house burned down and my collection melted and long gone. Maybe my wife has, finally tired of my childish hobby, taken and pawned the collection. Maybe a burglar has absconded with it. Maybe a raccoon has gotten into the house and pried open the case and sprinkled my collection across the floor. Maybe I'm just in the Matrix and my collection is a series of 0s and 1s that are a figment or our collective imaginations, man... what do we really know... dude... ? But we settle these kinds of beliefs by looking out at the world:
IS
it the case that this belief is an accurate reflection of the state of external reality? That and that alone makes such beliefs true or false.
Opinions are often used to indicate the sorts of beliefs that might track more closely with subjective preferences or value judgments, or at the very least the sorts of beliefs that are non-empirical. They tend to deal with issues that are more subjective than objective. For instance, someone might have the belief that access to basic healthcare is a fundamental human right, or that a hot dog is a sandwich, or that Ant Man and the Wasp is their favorite MCU movie. Here you have a moral issue, a conceptual terminological issue, and a matter of taste. We cannot resolve these by going out and observing/measuring the world. We could evaluate them, support them, or challenge them in a variety of important ways, but they are very different than other kinds of beliefs. But we can't ask
IS
this sort of belief an accurate reflection of the state of external reality? We might ask
SHOULD
we as a society treat access to basic healthcare as a fundamental human right? Put different,
ought
we have a duty to provide such a thing?
Should
we call a hot dog a sandwich, or is this a gross misuse of the term?
Should
someone think Ant-Man and the Wasp is their favorite MCU movie? Asking these kinds of questions is, in some case, of utmost importance (what are our human rights and duties?), and in some cases occasionally of practical import (well, if a sandwich place has a non-compete clause as their agreement with their leasor, can that leasor lease out space to a hotdog vendor as well, or does this violate their contract with the sandwich place?), or of utterly no practical significance (does it matter what another human being's personal tastes and preferences are with regards to their enjoyment of the MCU?).
