This is Tiffany, walking back home. Start with the boots. They are big and heavy boots, much repaired by her father and they'd belonged to various sisters before her; she wore several pairs of socks to keep them on. They are big. Tiffany sometimes feels she is nothing more than a way of moving boots around.

To summarize: it is a well-known fact that those people who must want to rule people are, ipso facto, those least suited to do it.
To summarize the summary: anyone who is capable of getting themselves made President should on no account be allowed to do the job.

Douglas Adams — The Restaurant at the End of the Universe

The first one instantly made me think of Douglas Adams

Terry Pratchett Discworld books? From memory the ones about witches at least had a good bit of it.

Check out Ann Leckie's Ancillary Justice series.

For a long while you're not actually sure what species the characters are, what their defining features are, if they even have gender, and/or how many limbs they have.
