We happen to live in an era that is incredibly wrapped up in notions of political correctness; everything is seen through the lens of politics. But being political and politically correct is just another way of fighting, another form of power and strategy, an insidious means of manipulation.
When there are no other options, people fight harder. If the choice is life or death they have nothing to lose.
As a writer you know you don't have to deal with a lot of the crap that most people deal with, the political things. Every couple of years when your book comes out then you have to go into these fights with the publisher and the publicist and that's it.
