Answer:
These are the ways in which the culture of marriage in the United States reinforces heterosexuality as a cultural norm.
Explanation:
Sexuality is often imposed on human beings as a social construction, where the culture around us and the concepts and customs defended by it determine that heterosexuality is correct, desired and expected from each of us. While homosexuality is seen as something wrong and culturally combated in the strongest possible way.
Our culture presents marriage as a way of teaching us about heterosexuality and as a way of imposing that this type of sexuality is desired by us. This can be seen through the prohibition of homosexual marriage and all the prejudices carried by homosexuality, which imposes on us that homosexual couples are unhappy, because they do not fit in the heteronormatized culture, which causes suffering, and, nobody wants to suffer or be unhappy.
On the other hand, for cultural reasons, marriage is shown as something heterosexual, happy, easy and that promotes improvements in everyone's life.
