Well it's certainly not a 'fixed' term on what is perceiced as the 'Left'. A while back during the SSP 'happy phase' there was a meeting on mutli-culturalism. What became increasingly obvious was the inter-changeability, both deliberate and not so of 'multi-culturalism' and 'multi-racialism'. The two were being used to define the same thing and yet, imho, were and are not the same things at all. The accusations that flowed as a result of a small number of us questioning the former and questioning the Left championing state/official/top down multi-culturalism made this clear. No-one questioned, opposed, rejected or bemoaned the muti-racial society we clearly have, yet by criticising multi-culturalism you'd think we were donning a black/brown shirt and thinking of a March on Cafe Roma. Anyone who questioned it was accused both overtly and covertly of being a racist and with a side order of Islamophobia. The inability of the Left to defines the term correctly is still a major problem.
