I think the school of thought behind the legislation runs something like this though Naomi. If you stop discrimination being socially acceptable in public, in fact if you make it illegal in public, it's prevalence wanes until eventually a more acceptable society emerges where thoughts of racial superiority really are in a minority, and it's then that the legislation has really succeeded, because then people no longer hold those opinions even behind closed doors. this is obviously not a five minute fix, but takes place over many generations and this is why in my opinion racism no matter how ' trivial' it might seem to some people needs stamping on at every opportunity.
