The r/writing subreddit Principle 

The r/writing subreddit Principle states that if your question starts with the words "Is it ok" or something similar to that then the answer is invariably yes.

"Hello, r/writing. Can I use a particular gimmick or a plot device that has been used before but because I don't actually read books or do any research I just assume it to be a highly original idea?"

"According to the r/writing subreddit Principle, the answer is always yes. You can write whatever you want."

"But is it ok if, like, my main character dies in the end? I'm afraid the average reader will be put off by my creative genius."

"Yes! Stop asking other people for validation! Grow a backbone and write what you want!"

Safe Space Subreddit 

A place where a group of people can gather if they have been subjected to ideas that differ from their ideologies. These safe spaces have circle jerks, pointless discussion and a delusional moderator team. Presumably, this allows them to recover from the trauma; free from any lasting damage resulting from exposure to ideas that conflict with their beliefs.

The subreddit /r/The_Donald is a safe space subreddit for Donald Trump supporters
