You feel there is some bias in favour of ethnic minorities is prosecutions for "hate crimes"? Any actual figures to back this up?
Experience! Being abused for being white is not uncommon and trying to get someone charged, over the last ten years, has been totally worthless effort.
You personally are involved in charging people for hate crimes?
I have been abused, long and loud and unpleasant and complaints - the last one about five years ago - merely got me told to "grow a set and to stop being so sensitive".
I gave up bothering. These days I don't bother even listening.
