This is an important point. We have an ongoing example of discriminatory language by members of - of all things - Yorkshire County Cricket Club. A player of Pakistani heritage but born in Yorkshire (a qualification for players at this prestigious and ancient club) has retired and accused the club of racially motivated language. This is almost certainly the use of 'Paki' in what the club dismissed as dressing room banter.
The standard response for 'banter' of this kind goes like this: 'Can't you take a joke?'
[Note that despite the 'banter' he represented the club (and was paid like the rest of the team); he was not discriminated against professionally. He has not suggested that it was more difficult for him to make the first eleven.]
I don't know the history of that term or how it was used. If it's an incident of racism or not I cannot say.
That's not what is happening here.
In the US racial discrimination is a crime. The necessary factor for determining guilt is evidence of intent. If a business doesn't have any latino workers....we can't just assume they are guilty....we have to show they never considered Latino applicants. If they haven't had any latino applicants, they can't possibly be guilty. Make sense?
The reason why intent is necessary is the concept of innocent until proven guilty. It's a really good idea if you want to avoid witch burnings or lynchings and class based punishment.
We have a political party that has bought into the idea that we should just treat all white people as guilty whether we have any proof of racism, racial discrimination, or not. The whole of an entire race is guilty.
Even if you are poor, uneducated, and never met a minority in your life....you're guilty because of the deeds of people who look like you in the past. This idea is the justification of the punishment of anyone white. You should shame them, deny them opportunities, remove them from positions of influence or power.
It's an extremely racist idea that has caught on rather quickly.
I used to think of the racists of the past as hateful or ignorant but really....now I realize they were dumb. The majority were just idiots. There's the occasional opportunist using ideas like this for gain...there's the occasional hate filled person. Now I just look back and think that the majority were simply too dumb or perhaps too cowardly to think for themselves.
