“I'm from the countryside... I went to work in the city and took the subway on a rainy Friday to go home. My friends at work were offended when I said those fences looked like a cattle pen. I didn't want to offend, because I was part of the herd.”

I don't know who wrote it and it was difficult to translate it into English because of the slang, but this story left me thinking… 

 That's a great analogy for self censorship.
