No, opinions can be true or untrue based on real information. Your opinion, while entitled to it, isn’t inherently “true.” But it may be.
Let’s say your opinion is you can jump off a 29 story building and walk away. Your opinion is wrong. You can have that opinion, but it doesn’t mean it’s true or correct. My opinion is you’d probably die. My opinion is correct, right, true …. Whatever you wanna call it.
