An opinion is usually biased. There's a reason it is not a fact.

Not exactly sure what you're trying to say. If you work in a liberal city, your opinion likely has a bias. If you are at a certain educational level, your opinion likely has a bias. If you are male/female, your opinion likely has a bias. If you were raised in a poor/rich family, your opinion likely has a bias. All your life experiences contribute to your opinion having a bias.
