If you are inculcated with lies 24/7 day after day after day after day after day at some point you will believe them to be true. You have been brainwashed by those with ulterior motives. False memories also can be implanted for those who are very gullible. Especially is this true if those falsehoods comport with political beliefs you already hold. YOU WANT to believe whatever anyone says that supports your prejudices. So lies are the weapon of choice. Do the brainwashed bear any responsibility for the lies they believe/tell if they truly "believe" they are all true? How? Aren't they mentally dysfunctional due to the bad actions/intentions of others?
