Safety lies in catering to the in-group. We are not all brave. All I would ask of writers who find it hard to question the universal validity of their personal opinions and affiliations is that they consider this: Every group we belong to - by gender, sex, race, religion, age - is an in-group, surrounded by an immense out-group, living next door and all over the world, who will be alive as far into the future as humanity has a future. That out-group is called other people. It is for them that we write.
Ursula K. Le GuinA panda walks into a tea room and ordered a salad and ate it. Then it pulled out a pistol, shot the man in the next table dead, and walked out. Everyone rushed after it, shouting "Stop! Stop! Why did you do that?" "Becuase I am a panda," said the panda. "That's what pandas do. If you don't believe me, look in the dictionary." So they looked in the dictionary and sure enough they found Panda: Racoon-like animal of Asia. Eats shoots and leaves.
