I read this last week and Fraden attempts to explain the reasoning behind this phenomenon.He makes some good points but he may have missed the most obvious.The Bolsheviks who control Hollywood and to a lesser extent Madison Avenue, have for more than a century,at least in this nation,used minorities to divide the population.I don't know what they hope to accomplish,especially if these divisions lead to a hot war.Some old world nations banned them from participating in politics and the law.Perhaps it's just their nature to alienate citizens along the lines of race,religion and ethnicity,as they've done in almost every nation in which they've been hosted
Commercials take up 27% of commercial television screen time and are the main source of income for TV and radio stations. In most cases, advertisements on all channels appear simultaneously, so don't try to change the channel, there will be commercials elsewhere, too. Nowadays they have also taken over the Internet. For financial support, websites have to run ads on their pages, the largest share supplied and controlled by Google. Ads pry into your eyes, unceremoniously interfere with text, and on YouTube, in the most inappropriate places, they cut into the action of films, lectures, and concerts, tearing apart musical performances. There's no escaping commercials, we've grown accustomed to them, and they become almost as much a part of our lives as food, toilets, and sleep.
In the United States today, the White population (not including Hispanics) is 57.8%. In real life, Caucasians are still in the majority, but now on TV and the Internet, they are swept under the rug like trash. Blacks comprise 14% of the U.S. population but appear in 50% of commercials. White actors now appear to promote health insurance, gold, loans, and some medicines. Moreover, if a White person appears in a commercial, he/she is usually old, sick, a freak, or at the very least, an appendage to a Black partner. If there's a doctor on the screen, he's usually Black, while the patient is usually White. Caucasian young men appear in only 4% of the commercials! If some aliens began to study the population of Planet Earth through our TV commercials they would have a somewhat distorted picture of Americans, to put it mildly.
So why do advertisers ignore the long-standing rules of marketing, and to the detriment of their own financial interests, fill the media space with content that displaces and degrades its biggest market segment? The answer is simple. At the heart of this nonsense is political correctness in a form even an Orwell could not have foreseen. Business executives go out of their way to publicly show their conformity with the universal “diversity” and "critical racial theory" (CRT), demanding that the White man be blamed for all the sins one can imagine. Replacing ancient, long-vanished oppression of Blacks with real oppression of Whites, overcompensating and planting racism-in-reverse.
Why does the White population, which is still in the majority in the U.S., accept the banishing and belittling obediently and silently? Why is there no public criticism, much less resistance to the idiocy? Why don’t people don’t tell political correctness to go to hell? After all, the U.S. is not Stalin's USSR, and anyone who disagrees with the party is not yet sent to a camp or shot. Why is there such stifling conformity among the American people, formerly known for their independence and freedom of speech? The answer is simple and sad: the reason is fear, albeit on a more vegetarian level than it was under Soviet rule.
Ordinary people keep their mouths shut for fear of losing their jobs, not getting a holiday bonus, not getting promoted, or being socially ostracized This is understandable, and I wouldn't blame them, although I wouldn't respect them either. But what are people of higher position afraid of — the heads and owners of businesses? What is threatening them? Indeed, nobody is going to drive them out of their positions or take their business, though fear of boycotts can be realistic. They are afraid of various inconveniences: negative articles in the leftist press, social shunning, frivolous lawsuits, loss of state and federal licenses, government contracts, unexpected audits by the IRS, fines for alleged violations of minorities’ rights, and the like small and large troubles.
