Vanilla isn't "blank," you get it from the fruit of a tropical orchid. The flesh tone known as "white" is pinky-peachy-orange and it’s hardly the global standard. Political left and right wing aren't places, and you'd drive forever trying to find their midpoint.
There is no such thing as neutral.
There's no relationship without tension, no progress without compromise, no flawless Tweet, no timeless aesthetic. These concepts only exist in utopia, and utopia literally means "no place."

What feels like a neutral opinion is a culturally, linguistically, economically, physiologically, chronologically, et. al., informed point of view. You most definitely have a bias because you carry momentum from the beginning of time.
