Your example is just one of many I've seen. The entire instance seems to be engaged in an opinion shaping campaign where only this gross mix of Western doomerism with Russia/China-glorifying fascism is allowed to thrive.
I don't know how to best deal with such indoctrination chambers. Their members become completely divorced from reality and there's no way to pull them back from the brink because anything you could say to that effect gets moderator-deleted. Yet vice versa, they can freely spread their propaganda and engage in "raids" on other instances.
