Do you honestly believe that advertising is a legitimate and useful source of truthful factual information that people should be using to make decisions and shape their thinking about the world?
Do you honestly think that there is a single "useful source of truthful factual information" on this planet? There is not a single organization out there that will not present you facts without some sort of bias or slant.
I would love to watch you tell me in person that you believe that targeted advertisements are as good a source of knowledge and information as any other on the planet, and try to keep a straight face while doing so.
Who cares about having a conversation with someone who rejects the idea of any outside sources of information being accurate since you can never reach any sort of consensus on objective reality with them?
