I suppose the honest answer Kazzie is that I don't really know. I live near Blanchardstown and the are uses to have loads of foreign doctors. they integrated, spoke english, married Irish girls, etc. We got on great with them despite the cultural differences.
Now, however, there are an increasing number of financial imigrants. They don't integrate, and make little or no effort to meet locals or get involved. I suppose this is because they don't intend on staying here for very long, whereas the doctors were here for the long haul.
I regret to say it has changed my opinion. I suppose there is a racist streak in everyone, once its tapped into. Whether or not it has actually resulted in racist behaviour, I'm not sure. Blimey, I hope not.
