Well they feel alienated since right-wingers can still count on the state and capital to follow along with their ideology, but culturally they feel confused since movies, shows, advertising, etc is captured by ideological liberals. Right wingers have basically everything they want in terms of political victories at the moment.
By that I mean they’re winning when it comes to actual enforcement of racism and transphobia. Structural bigotry is still rampant and is getting worse. And this is at odds with American popular culture, which is will often vaguely gesture in the direction of progressive values. There will be gay characters, or trans characters, like little progressive snacks for suburban liberal types.
