Starting with the ones you think are the biggest blot on our society. (Number them 14-1 if easier)

Recruiment Agents
Paedophiles/Child abusers
Chavs/Hoodies
Murderers
Racists
Gypsys
Estate agents/landlords
People who stay on the dole forever
Traffic Wardens
Politicians
The Police
Sexists
Drug addicts
Animal testers

No need for me to number them because thats pretty much my list.
