Re: What a nice list
Personally I like living in a country that allows me to text my best mate with "Morning you rancid cum bucket, I hope you didn't take that rancid munter to tuna town on your spam bus last night" but I like in a culture where we take a personal responsibility for our actions.
That said, if I'd been brought up ina different culture or am texting someone else who was brought up in a different culture you have to consider that you may not be operating in full awareness, for example, I don't believe that anywhere considers "Brit" to be a derogatory term, whereas "Paki" is often, and so using it might cause offense, for the same reason, just because "Nigger" is derived from the latin word for black (or wrongly often thought to be from Nigerian), it doesn't mean that it's OK to use, just because you know where the word came from. For the same reason, the word "Boss" is not used in some parts of the world as it had been used for a white man owning slaves, so the word is avoided.
This is not a double (or even doble, which I believe was someone from a district of Vienna) standard, it's called cultural awareness.
