What are some good topics or themes that I could to use to lead a class discussion pertaining to Olivia Butlers, Kindred?

This fascinating novel
clearly concerns the theme of slavery and our relationship with it, both today and in the past.
There are a number of sections of the novel where characters realise that the wall protecting
them and separating them from the radically different world of slavery in their own country just
a few years ago is actually very porous. This should lead us to really think about and consider
what the impact of slavery and the kind of violence, segregation and complete power that whites
over blacks have in this story impacts us today. Through the motif of time travel the author
allows two very different worlds to collide, and this collision changes Dana permanently
forever. How does the novel change us?

Secondly, you might like to think
about some of the choices Dana makes to ensure her own survival, both in the past and then
through trying to ensure her survival in the future, as a descendant of the characters that she
meets. Was she right to persuade Alice to sleep with Rufus so that she wouldn't be beaten again?
Should she have tried to teach some of the slaves to read? An important aspect of this story is
the way in which the author suggests a different moral code was in order from the Christian idea
of ethics. In such a world of slavery where you are deprived of every right, is it morally
acceptable to sleep with your white master to avoid torture and pain? Such issues force us to
evaluate our own morals and ethics and to consider how context-specific they are.

These are some issues and questions that should get you started. I have provided some
links below that should also help. Good luck!
