Morality Some opinion can be true/false though. — creativesoul
<sigh> as we laboriously lay down some kindergarten-level material: There are different senses of the term
opinion. One sense is how a person feels about something. Whether they like or dislike the thing in question, whether they approve or disapprove, etc. That sense can only be true or false re whether the person is honestly reporting how they feel, and insofar as the sentences are framed more or less as "I feel . . . ," "I think . . . ," "In my opinion . . .," which they often are not. (For example, people often say "Beethoven is the greatest composer," rather than "I feel that Beethoven is the greatest composer." The former can't be true or false.)
The second sense of "opinion" refers to a person's view on a factual matter, where there's often an emphasis on the views of persons with some expertise in the area in question, and on matters that are still up in the air if not outright controversial epistemically. So, for example, we might query a cosmologist's opinion on dark matter--query exactly what the cosmologist believes dark matter to be. This is not querying how the cosmologist
feels about dark matter, whether they like or dislike it, etc., which is unlike the other sense of "opinion." And unlike "Beethoven is the greatest composer," something like "Dark matter is simply an issue of having an incorrect model of physics, so that our gravitational formula are wrong at least in particular circumstances" can be true or false without needing to add "In my opinion" to it.
There are different senses of the word "opinion." Only one sense can be true or false when stated without an "In my opinion" (or equivalent) clause. You should have at least learned this in school as a little kid--by second or third grade, say.

No.
