Just off the top of my head:

• Gypsies & travellers
• Jews (duh)
• People with mental health problems
• Unemployed people
• People with the wrong regional accent
• Academics and people with university degrees
• People who voted for Jeremy Corbyn
• People who have the wrong internet connection records (great now the Home Office has those isn’t it?)
• Cyclists
• Vegetarians
• Hipsters
