So you're saying to *deface a war memorial is "disgusting" ... but let's leave it at that!? It's tantamount to sacrilege, John - and should certainly not go unpunished - regardless of the perpetrator's race or creed!
Say, for instance, a passer-by spotted a swarthy-skinned man *doing something along those lines and immediately reported the incident to the police. And the witness - assuming the felon was a black muslim - said as much in his/her statement when asked for a description. In effect, by your reckoning the complainant is just as liable - as the person committing criminal damage - to be prosecuted for 'racism' ... simply because he/she unwittingly referred to the offender being of a dark complexion ... and perhaps wearing a garment consistent with that normally worn by someone of the Islamic faith.
Come off it, John ... that's taking things too far ... even in these days of so-called 'political correctness!
