Yes it's better to block out whatever the dominant media is throwing at you, and be independent. Otherwise a girl can get sucked in as I have. That experiment was first done way back in the 1950s. It's been repeated a few times since then and didn't have the same one sided results.
A person is only "sucked in" as far as that person allows him/herself to be.
Human nature says: There are no mistakes...only Lessons; Lessons will be repeated until they are learned. Learning does not end. You will forget all this at birth.
