Apologies for the late reply, I have been away. I enjoyed reading your interesting analysis.
You make a good point about the 2 four-letter P words. Originally Poms was an insult, but nobody takes offence at it nowadays. Conversely, the other P word was used insultingly, so that offence is always taken when it is used.
The local corner shop is run by an Afghani (that is what he refers to himself as). I dont know if that is viewed as offensive if used by other nationalities.
I have been called many things: Pom, Pape (another 4-letter P word), Mick, Scouser etc. I have never taken offence at any of them.
