Unfortunately these days there seems to be no difference between "discriminating between" and "discriminating against", so that it is now difficult to use descriptive language about a person without being considered 'racist'.
For that reason, any general discussion of the subjects of immigration, or ethnic integration, tends to become clouded immediately with claims of racism. For this reason (it seems) the major UK parliamentary parties avoid raising these questions. It is this unwillingness to appear to recognise any difference which allows the BNP to say that no-one else is doing anything about immigration/integration.

Azizi raises the matter of how Christians should view this. It was there even in Christ's time. The people of Samaria were considered 'outsiders' and not the equal of the local peoples. Jesus highlights this in the parable of "The Good Samaritan" pointing out that this member of a 'lesser' people did the right thing whilst the Priests & Levites (the 'great & the good' of the local people) passed by on the other side.

How little things change!
