This is perfectly understandable. Not only is our world hurtling toward nuclear armageddon and environmental collapse while surging authoritarianism threatens our ability to even talk about these things with each other, but most people are completely oblivious to it all. Even relatively politically engaged people tend to believe society's biggest problems are things like sexism or drag shows, and they generally support one of the two mainstream political factions who are both driving us toward destruction.

And this is of course because we live in a mind-controlled dystopia where everything is fake and stupid. Western civilization is dominated by a power structure that has invested more heavily in "soft power" (mass-scale psychological manipulation) than any other power structure in history. It pervades our media, our internet services, our art — literally all of mainstream culture. 

The politicians lie, the news media lie, the movies lie, the internet lies, the advertisements lie, the shows between the advertisements lie. They lie about our world, they lie about our government, they lie about what's important, how we should think, what we should value, and how we should measure our level of success and worthiness as human beings. That's what you get when you live in a civilization that's made of lies, under an empire that's held together by lies.

So of course people who see this express despair. When you first punch through the lies and start to gain an understanding of what's really going on, it can be really unpleasant at first. It feels like what it probably felt like to be a lucid thinker back in much less enlightened times when civilization was dominated by religion and superstition. Lonely. Depressing. As Terence McKenna said, "The cost of sanity in this society is a certain level of alienation."
