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?
If I read a book and there was a detailed description of pigpoopballs I would be blown away. I would be showing that book to everyone I know.
I already had a innocuous mention of pigs, I can see myself trying to build up to the glorious people's ppb.
