The Decline of Western Civilization through the Lens of Art and Gender

The cultural critic Camille Paglia is a critic of identity politics, especially with regards to gender. She has said that the proliferation of different identities, the different gradations of gender, and etc., often happen in the late-stages of a culture, before the verge of collapse, where all kinds of amoral behavior result, such as homosexuality and sadomasochism, which are basically signs of decadence (her words, not mine.) Is there any truth to this? Do you think that identity politics, especially of sexual and gender identity, is a sign of the fall of Western civilization, specifically the United States? Give specific examples from art of any medium to support your claims about the decline of Western civilization.
