Let's face it, opinions change as our experiences increase over time... People change, not only in what they see and know, but even physically... We are fluid.
...But by communicating with one another, we're essentially keeping open doors to move about and gather information.
Sometimes this ability to garner information spills over, into abstract ideologies, which is what the worldview is. It's just categorization, even if it is true for some, I doubt it can be proven in a laboratory using the scientific method. So it exists mostly in the human mind's imagination, and not the physical world. There isn't even a doctrine on it in the majority of religions. So it should only exist where it's actively practiced, and left out of the mainstream as far as my experience can tell.
...I don't see any positive things coming from it in my life. Do you?
