I'm writing a currently genre ambiguous Sci-Fi/lovecraft/spaceopera/superhero novel that doesn't outright declare everyone is openly is Maoist/Anarchist/Stalinist/Etc., (the alien characters won't have human etymology for their ideologies) and maybe it's not actually all that political on the surface anyways, but any tips for slipping in vegan and leftist dog-whistles?
Class consciousness alone is a good dog whistle and easy to reframe in terms of a sci-fi situation. The trouble, really, is whether you want just lefties to pick up on it or libs to understand and internalize it. The former can be done with dog whistles. The latter you really have to hit with a sledgehammer and even then half won't get it.
never underestimate the important of tricking libs into reading theory.
