Re paleface and redskins. I'm sure they were racists terms as people seem to need to find a derogatory term to describe a race they don't like. It goes on worldwide
Indeed it does - there's a whole slew of derogatory terms for every group of people by another group of people. On the Isle of Man, you have Peel, which is all of 7 miles from Ramsey but people in Ramsey refer to people from Peel as Gobbags (pronounced Govags) which means 'little fish with a big mouth'; it just seems to be inherent in humans to insult one another!
I remember being told that Afrikaans term for the English is Soutpiel. They gave this term because the English have one foot in South Africa and one foot in England leaving, erm, a dangly bit in the salty sea. Soutpiel means 'salty penis'
and I'm pretty sure it's derogatory; I found it quite amusing and displaying an air of imagination in the insulting stakes 
I also read that in Germany, the British are known as 'Inselaffe' which means island ape/monkey; I suspect that may also be intended as derogatory 
Overall, I don't think the British care very much about that type of label and tend to laugh it off; none that I've ever met have ever expressed offence at them.
