Everyone should be appalled at the rise in hate crime since the BREXIT result and agree that the campaigns by the EXIT campaigners in some way made respectable the attitudes and behaviours of the perpetrators.
Under the circumstances it is understandable that many are calling for tough or mandatory prison sentences for hate crime even where the intensity of an individual act may relatively minor. (All hate crime has an impact and should never be regarded as minor but I am trying to differentiate scale). But prison may not be the answer especially for young offenders with a first offence.
In prison there will be no form of programme to re-educate people away from hate crime. No such programmes in prison exist. Even if they did they would be reserved for the most high risk and serious offenders. The best someone could expect if imprisoned for hate crime would be an anger management course which may be useful but does not deal with the issue. At best a perpetrator will come out of prison with the same mindset with which they went in.
