This is the fundamental problem. People think they should be able to do that. They should not.
It is extremely dehumanizing when some stupid ad works its way into my mind. I never asked for this. I never wanted it. They just keep forcing it. They feel entitled to it. They think it's their right to keep showing me this stuff. They think they own my senses. A couple seconds ago some asshole with a huge speaker just drove past my house blasting ads for what I assume was a local supermarket. Everybody thinks it's great. It's a nuisance but it creates honest jobs, right? How will the poor little companies get consumers otherwise?
Attention is precious. It should not be wasted on advertisers and their little brands and products. It's a privilege that must be freely given and punished severely if violated without consent. Like rape. That's what advertising is really. Mind rape.
