That's a pretty broad brush that's painting.
America is a contradictory society, it always has been. WWII is a prime example. America’s Army was racist and segregated, Black solders in this company and white solders in that company; not much had changed since the civil war with the exception that Black men were now allowed to be promoted to officers. So the picture emerges: a racist, segregated army going off to fight in a heroic battle against the world’s most racist brute, in the name of humanitarian values. Protesting against Hitler’s putting Jews and other ‘undesirables’ in camps while at the same time themselves putting Japanese in internment camps (an edict ordered by the most liberal sitting president in American history)—I can think of no greater manifestation of America’s tendency of holding the good and the bad simultaneously together in one unholy mix.
"We hold these truths to be self evident, that all men are created equal..."
The same people that said those words themselves practiced inequality; many of them were slave owners (Thomas Jefferson, George Washington). George Washington definitely thought that Black men were about as equal as a case of molasses, which is the exact price he sold one of his slaves for. Most of the men who believed that ‘all men are created equal’ believed the Native Americans to be hindrances to the spread of ‘civilization’ and fit for either removal or death, “the only good Indian is a dead Indian” was the slogan. Don’t forget that ‘all men’ excluded even most white men at the time because they did not meet the property ownership requirement.
Or John Brown
A hero indeed, one who was hanged and had most of the male members of his family (including his sons) hanged because he stood for human decency and fought to achieve it. The point is that these men stood opposed to the prevalent culture of their time, they were not manifestations of it. John Brown, in American popular culture, was demonized and made into a despicable arch villain. He was not redeemed until the 20th century.
Harriet Tubman, as well as her abolitionists and Quaker network of friends, would have been hanged as well if they were caught.
Sticking to the point that Serge implied and Samer expressed. Look at how this sex industry finds itself in Russia; they have drive-thru order-a-prostitute-to-go services! In the West, the sex industry is Hollywood. It is glamorous. It is the strip clubs that we are supposed to go to for our bachelor parties, it is the unheard of brothels that follow US solders to Vietnam and ports were sailors are stationed. Ten years ago Eritrea used to brag about not having any prostitutes walking the streets. After the Ethio-Eritrea border war, and the intervention of UN troops, that has all been flipped on its head with brothels all over the place in Asmara (the Eritrean capital) to cater to the needs, and demands, of UN solders.
