The way i see it is this-

Rascism exists to varying degrees in all sections of society and stems from a fear of other cultures, which stems from an ignorance of these cultures, which stems from lack of integration...which stems from rascism. It's a vicious circle. How to break the circle? A concerted effort from all parties to inform and educate, and most importantly frank, honest, open discussion. By stifling this, political correctness has encouraged that which it hoped to eradicate. There are no quick, easy solutions.
