It's the world people like this live in. Reality is irrelevant and can be reshaped at a whim if we all just lose our false consciousness. They love using the Matrix as an allegory, even the creators retroactively call the movie a "trans" film after they both transitioned. If they can redefine words like "woman" then they'll finally get to live out their dream of being an anime waifu. It's why they spend hours and hours in VR chat as a catgirl instead of engaging with real life.

The sad truth is that these people are neglected, lonely, and underachieving in life. They've been robbed of their life's core purpose or even a chance to develop it. Likely they suffered childhood trauma and are disassociating. Because if you can become someone else you don't need to feel that pain anymore, right?
