Yes, but they don't do it with fucking flashing images and bullshit like that, holy fuck, lol
The brainwashing is done by warping your perceptions of reality; carefully controlling stereotypes. A quick example is how cars always explode in hollywood movies. A lot of people think cars really work exactly that way, because they only ever see it happen in movies that way, and have never seen a major car accident in real life.
So this is how they control and condition people: They create false, positive or negative, stereotypes and then constantly reinforce them by repetition. Any source of information that might upset the stereotypes they create are censored and discredited. Multitudes of media are used to reinforce the stereotype. The stereotype is further reinforced by classic rhetoric - fallacies, appeals, etc.
In this way a certain narrative is created, and people believe it 100% because they've never been shown nor have they seen or experienced, anything different. Blacks are gentle, caring, intelligent, and aboriginals are noble savages because those being influenced don't have personal experiences with blacks or aboriginals - only experiences filtered to them through mainstream and "popular" (isn't really, they control the popularity charts) media and culture.
And because this is done in a non-intrusive manner, the person in question thinks THEY came up with these ideas first, rather than it being drip-fed to them by the media. This helps reinforce the conditioning, as people cling to it HARD. You can't argue someone out of this condition, you have to lead them in such a way that they lead themselves out of it. This usually involves exposing the entire media establishment as liars, or at least exposing serious lies they've been led to believe their entire life, which will lead to them beginning to question the basic assumptions and stereotypes they've always believed but can now correctly see are distinctly not their own.
Television is nothing more than a brainwashing tool. The arguments, rhetoric, everything about it, especially the mainstream news channels, is about brainwashing you. Even the shows you don't normally think might be about brainwashing, are brainwashing you. They collectively control what you think the world looks like. When they control your sensory inputs, they control what you see, learn, and understand.
Drop television like a rock. Try to stop watching television shows and movies (the more modern, the worse it is).
