Oh, ecofascism is very real. Society in general has a massive ableist bias, and the media play a huge part in promoting that. Disabled people and those with long term conditions are often framed as basically disposable. It's everywhere, but it really feeds well in to the often white supremacist and otherwise privileged liberal "eco worrier" movement, but also right wingers who hide their genocidal intentions under a guise of concern for the environment, and even some anarcho-primitivists who insist we "go back to monke" without any regard for the lives of those who depend on technology and modern medicine. The more you look, the more of it you'll see.
