Back in the good ol' days here in the UK, it was common to hear people saying to other people who appeared to be of Asian ethnicity,''Paki go home'' ''Fuck off back to Pakistan'' or to people who appeared of African ethnicity, ''Get back to the jungle where you came from''.
These comments were made without regard to whether the person was actually of Pakistani heritage or not. Bangladeshis and Indians were lumped together with Pakistanis. I'd guess that the person shouting ''Paki go home'' had not bothered to find out whether the recipient of the exhortation had actually never come from that country or whether they had been born in the UK. Skin colour and appearance seemed to be sufficient justification for the comments.
But to think that the person doing the shouting could have a racist bone in their body is beyond me.
Ah the good ol' days when you could tell Pakis to go home.
