I don't get it either. My hypothesis is that they want an alter ego to disassociate from their shitty lives. It's probably a similar mental process to people who spend way too much time in video games, social media influencers, and people who watch too much TV. I think all these people are living lives vicariously through their animal personality, game character, fake media personality, and TV characters. These people need to work on themselves and find-out why they have an empty hole that needs to be ignored or filled with external validation.
