Not a day goes by without mass outrage being directed at a person or event for some sort of indiscretion - it's just how social media works.

But with so many racist comments, rape jokes, and disputed court verdicts, you may have forgotten many of the things that outraged you these past twelve months. 

Thankfully, Slate have compiled the most rage-inducing event of each day this year, and laid them out with some context to help you catch up.

Do you remember the hotel that wanted to charge guests for bad reviews; Facebook manipulating its users; or the supermarket with anti-homeless spikes?

Time to get angry all over again.
