I think a lot of the increase in reports of hate crime can be attributed to the fact it's now so easy to just go on-line and make a report. Prior to True Vision and hate crime apps people had to pick up the phone or go into the police station.
Don't get me wrong - hate crime is awful be it race, sex, weight or anything but it's always been there and I do believe it's now easier to report it than ever.
Calling someone fat, ginger, ugly and many other things is now classed as hate crime. I'm sceptical that the increase in these incidents has also been fuelled by brexit to be honest.
