>was giving my own opinion so it by definition can’t be false.
This statement is false and therefore your opinion could be false. Example, in your opinion white bread is the best, I think wheat bread is the best. Are you right, just because you believe it and said so? Obviously we both cannot be right. But to us, you and I, the statements are true.
They’re both opinions so they are statements of what we think. We are the arbiters of that so get to say whether we think them or not. That you like wheat bread and I like brown bread are both true and not false.
