We are all brainwashed to a greater or lesser degree. There are those who prefer being brainwashed and resent any intrusion of the truth, and there are those who although brainwashed would rather not be and who welcome the truth. No one believes they are the former. Everyone believes they are the latter.
The truth is available to those who want the truth, but it requires some effort to seek it out. Lies are available for those who don’t want the truth. No effort required. They will come to you. Just don’t question them.
Brainwashed: Inducing a set of beliefs in someone by controlling the information they receive and by applying peer pressure.
