There's lots about the human experience that you can't control, and advertising works on those levels too. You are affected by the mere exposure to it. You're not just sold a product - you are told about the brand, values, how they approach the world, how it's acceptable in these times to express yourself, lots of stuff. And you see it and you learn it. It doesn't really matter what you think about afterwards, you are already affected, because that's how humans work, and advertisements are exploiting how humans work. The solution is to not be exposed to it in the first place, and because you can't really block them all, to accept that you are affected and work with that. Denial will bring you nowhere. But, it can be a good milestone to realization.
