So maybe the copper was of Irish descent.
Does that then mean it could have been a racist comment?
no.
to be analogous youde need to say to an Irish police officer
'you spud-eating dumb mick bastard'
white Irish is an ethnic minority in Great Britain.
any white person who says they are offended by being called white is confused.
they are actually nostalgic; annoyed that they can't vilify brown and black people like they used to.
people have never been subjugated, enslaved, degraded on the basis of having white skin.
its really not that hard to understand.
