QAnon may be crazy, dangerous nonsense but it instrumentalizes a sentiment that isn't crazy at all:

The rich and powerful people who govern this country, every single one of them, would harm us and our families in the cruelest way possible out of as little as sheer whimsy. It's usually money, but whimsy is also a factor. The liberal institutions that were built to support the stability of all Americans have now been re-directed to protect the wealthy and to bind the poor.

There is no durable solution to this problem as long as we're guided by a constitution that elevates the bourgeoisie and tethers us to serve them. The United States depends on that structure for its existence, and so there is no form where it can continue to exist and still serve people in a way that will heal people's faith in liberal institutions. This was broken way before Trump, but he shined a light on it and so he gets to be its avatar. In any event, it doesn't matter who's fault it is now that it's done. You don't just defeat fascists in elections, something a bit more thorough is needed to address the issue.

In addition to being crazy, I think QAnon is such an impotent answer to this problem because even though it's politics are fascist, its aims are really kind of tepid and liberal. Thinking that prominent Democratic politicians are running an enormous, pretty public child abuse/murder/trafficking ring is pretty standard conspiracy theory stuff. Thinking that the charisma and will of Donald Trump (with some help from, uh, JFK Jr.) is going to fix it by brazenly arresting these prominent and influential figures is the genuinely weird part. And the end they're pursuing is just the restoration of trust in American institutions. No empire that lasts a thousand years or a grand new title for Trump. Just the justice system arresting the correct bad guys. Incredibly lame. They can't even do fascism properly.
