What they are really talking about is what they're not completely self aware about. In some sense, their worldview is being 'destroyed', because reality isn't lining up with how they see things or want to see things. Part of this is due to a lot of the changes happening socially and technologically. They don't understand any of this complexity though and find people to blame when it isn't even really down to individuals or specific groups. It's all of the large sweeping changes happening that is culturally leaving them behind and causing them to deep down feel irrelevant. The thing is too, with consumer culture in capitalism, these people are used to passively receiving affirmation for who they are and have been, culturally (- mostly white), so when the cultural shifts happening now involve more active redefinition by people of colour and others, they find themselves frustrated at their lack of ability and power to mold an identity because they're used to passive affirmation by spending money to have other people provide them with definition. The other part of this is that the technology present culturally, like the internet, has been radically changing how we shape our identities and people on the right are aligning themselves with a limited hive mentality that is very basic. Hives or swarms form all over the internet, but there's more diversity to be had outside of the internet media of the right, which is very impoverished in its language and messaging. It's why their speech is basically just repeating phrases and not trying to think of original ideas or articulations.
So with a lot of these things considered, a lot of the rhetoric of the sky is falling with conservatives is close to some truth in that for decades culture has been shifting away from the limited authoritarian way they identified with. It's always the case, the right aligns more with a status quo that is ultimately impossible to maintain because it's beyond anybody's control in the long run - if humans are able they could tend towards social diversity not repression (which we're still at a very early stage with in tandem with technological developments). Unless genocide, which is why the slope is danger, potentially, with authoritarianism. In many ways, the technological landscape of media can't really support authoritarianism if its open. The right would have to bring things to China like levels of control if they really wanted to alter or slow down the cultural shifts of our time. And even then, its still a limited sovereignty in the face of the overwhelming dominance of tech and media in our lives now.
