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?
Again, not subtle. You need to name specific groups to make clear what you are saying, not innuendo.
again I think if you tie it in with themes it could work
