I am a United fan, whose step-dad was at the match and do not like the implication you're making.
The police cover up after Hillborough is the most disgusting act of corruption committed in this country in at least the past 70 years, for which South Yorkshire Police can never be forgiven.
I want nothing more than certain officers to spend their final days rotting in a prison cell.
However someone just having a different opinion, however misguided, is not (on its own) offensive.
Being hopelessly misinformed is not a reason to lose your job.
