>> "Ads are a soft form of brainwashing" Every input we receive to our brains could be said to be a soft form of brainwashing. Good advertising serves a use for consumers. Without it, you wouldn't be aware of what you can buy/do etc. If you want to opt out of that, fine. Personally, I find it invaluable to be aware of what is going on.
No, a constructive argument showcasing pro's and cons and highlighting merits of competing products serves a use for consumers. And while that also has a soft brainwashing effect, it actually adds some information that allows you to make a conscious decission. An ad is just the brainwashing.
Word of mouth is still the best form of advertising though - agreed. That's not to say other forms of advertising aren't effective, or useful for the consumer.
For example, I know what movies are out mainly through billboards. It's useful to me. If one looks interesting, I might look it up on the net and see if I want to go see it. I'm not being 'soft brainwashed', I'm being informed of a new movie I might want to go see.
