Most everybody is familiar with the modern television commercials that depict white men as dufusses (dufii?). Of course, the women are naturally depicted as competent, intelligent and mostly tolerant of the incompetent man. Supposedly there is humor in there somewhere.
Well, you get the idea. Why does this happen? The short answer is: it is because there is only one group left in the US that one can mock; and that would be white men. Now onto a longer analysis.
Commercials very often try to be funny (note the word try). Why? Because funny commercials are more memorable than non-funny ones. And the point of the whole effort is to be memorable, not to convince the potential consumer that product being sold is better. In short, being memorable sells; and the consequent branding sells. Funny commercials need something to be funny about, and with women making the majority of buying decisions, the target of jokes are naturally men (but only white men). That is the dollars and cents analysis.
But there is more. White Men are the decedents of men from the Evil Patriarchy (they are also decedents of the women oppressed of the Patriarchy also, but that does not matter). These modern day white men even carry the surnames of the men from the Evil Patriarchy (so do the women of today, but that is of no matter). Because White Men are White Men, they must be collectively punished for the supposed sins of their ancestors (but White Women who have the same ancestors must not be punished). So mocking White Men ends up being a twofer; it makes good business sense, and makes one feel good about punishing a group than is deemed worthy of punishment.
One would think that this type of foolishness would stop during such events as broadcasts of American Football, which is considered the most manly of the major sports in the US. But this is not the case; as the commercials bashing white men are unrelenting. Perhaps doing this during football games is viewed as a special rubbing one’s face in it act by the people who push this stuff. Still, the men take it.
