On the other hand, the United States is the largest and most conservative Christian country in the world. There is a vast "Bible Belt" in the south-central United States, which is famous for evangelicals and fundamentalist Christians, and the social atmosphere is extremely conservative. In this region, both the elite (such as George W. Bush) and the grassroots (nicknamed "Red Neck") have zero tolerance for same-sex marriage, and even abortion and premarital sex are not allowed by law or morality.
But at the same time, as a multicultural immigrant country, the United States still holds a very strong position except Christianity and conservatism. However, the idea of American liberal elite is to respect the free choice of others. Sexual freedom is put forward at the level of liberating human nature and opposing moral oppression. Sexual freedom does not mean promiscuity and one-night stand.
Most of the sexually confused groups in the United States are African-Americans and "Matt-killing" whites. Generally speaking, the tolerance of "promiscuity" in American society is still quite low (for example, if an American politician exposes prostitution or extramarital affairs, his political life is basically over half).
Let's talk about the situation in China. At present, there are a group of sexologists and liberals with ulterior motives in China. When introducing the west, they always regard "sexual freedom" and "sexual liberation" as the mainstream values of American society, but never mention conservatism. Even the controversial issue of legalizing gay marriage in the United States has become politically correct in some online communities and groups in China. You know, anti-gay demonstrations can be organized aboveboard in America.
In this case of asymmetric information, many teenagers in China regard homosexuality as avant-garde, virginity complex as shame and promiscuity as progress and glory, which leads to the abortion rate and number in China being second to none in the world. Needless to say, compared with conservative countries such as the United States, even the French will be amazed at the sexual openness of the new generation in China.
In addition, I object to all the above answers that China is sexually open on the grounds that "China has a large population". In the primitive stage of population growth, the birth rate of newborns of all ethnic groups in the world was roughly the same, because China's ancient medical level and agricultural technology were more advanced than other ethnic groups in the world, and the neonatal mortality rate was lower and the average life expectancy was longer, resulting in a large population in China. In the same way, this can also be used as a reason to explain the sharp rise of population in western Europe after the industrial revolution.
