Some friends of mine attended a meeting recently of a writers' group that is made up primarily of women, most of them Romance or Mystery writers. The speaker for the day got off to a bad start when he indicated a certain fascination with a brutal serial killer who had preyed on women. He then proceeded to do a reading that involved the rather graphic torture of a female victim. Several people walked out, including my friends.
My thoughts? Know your audience, dude! And don't be stupid.
