There is no way of writing stories that I haven't done.
I teach writing courses and first of all, I teach my students what prosody is.
If All Men Were Brothers, Would You Let One Marry Your Sister?
In science fiction, you can also test out your own realities.
I wrote the very first stories in science fiction which dealt with homosexuality, The World Well Lost and Affair With a Green Monkey.
Basically, fiction is people. You can't write fiction about ideas.
