Secrets are evident in every aspect of life. In Sante's essay, there are three main reasons for secrecy: Soviet Union, internet, and confessional culture/media.
First up, the author discusses the Soviet Union. This was the part of the essay that was initially confusing, but I think that the main point of it was that people in the Soviet Union had to keep secrets because they didn't want to get in trouble with the government. This type of secret protects the safety of the individual who has the secret.This is not normally a secret that they would share with their close friends due to the possibility of the government finding out.
Next, the topic of internet comes up. The internet is one of the biggest places where people share secrets. Nobody over the internet knows who "animegirl27" is. These people feel that they are making real connections with other people, and that alone is reason enough to trust them with their deep secrets. However, Sante argues that the internet is one of the places where secrets can spread like crazy. Some people might in fact know who "animegirl27" is. Posting secrets onto a place where the whole world can view it is not exactly a very smart idea.
Sante's last thought is on confessional culture and the media. We live in a place where we feel insecure if we are the only ones feeling a certain way. Confiding in a close friend and letting them know the secret is a way that humans get emotions off of their chest and into the open. Being human, we have the desire to tell something that we know that we shouldn't.
