@ Hitech_luddite: While I totally understand your concerns, it is still you, the author, who decides what to write and what language to use.
You may offend some readers, you may enlighten some. As gastan says, nothign new under the sun, and definitely not fundamentally eBook-related.
Anf if you publish your work yourself you decide on which shelf your eBook will be put in any online store. If you use a publisher. he/she will attend to that fact.
Just write. Worry later.
