Don't think tuning commercials out makes you immune to the influence. If anything this allows them to seep into the subconscious. Joe Camel was exiled because he allegedly had influenced several thousand minors to smoke. Yet, in spite of trying to balance the gender scale, there are commercials run daily showing men as stupid and women as either helpless or as smart and resourceful blessings for the stupid male. That's worse than Joe's sins.
Lung cancer is horrible.
Smoking is not healthy. It is not OK for minors to smoke. But the commercials depicting these gender roles feed a society that is struggling to break a glass ceiling, seeking equality between the sexes. It's not funny to see men being stupid. It doesn't make me want to go to a particular mechanic or apply for a certain credit card.
