Advertisement, like any art form, is made of 90% garbage. The difference with all the other art forms is that there is a whole industry that works towards force-feeding the greatest number of people with that the garbage.
A few times I was so disgusted by a movie that I walked out of a theater. I don't have the choice to walk out of most advertising, I don't have a choice which advertising I see in the first place. Most of the ads are in the worst possible taste and dripping with hypocrisy. I guess you get used to it somehow, after all those years. I bet you could get used to eating shit too.
