Let's get contentious - the types of people you can't stand

People who blame "Political correctness" when anything they say or do that is racist/homophobic/stupid etc is criticised
People who use the term "hipster" for anyone that has a different taste to their own.
Extreme Michael Jackson and Star Wars fans
Men who wear shoes without socks
Young men with big beards
Conceited people
People who have to photograph everything they eat
People who still wear a festival entry wristband months after the event
Americans who every time there is a terrorist attack overseas think they are an expert on race , religion, security, politics, and above all , the place the incident happened, and decide to share their "advice" or what they would have done.
People who describe their job as a blogger or vlogger.
