You are right, I have no proof that anyone on this forum is a hypocrite. However, I live on the outskirts of a large immigrant area and my personal observation is that no white people of any political persuasion are moving in. So no difference in observed behaviour between outright racists and outright non racists!
My observations are that many people like experiencing other cultures but ultimately they settle down with people of similar culture. So, most white middle class people will live in a white middle class area with a sprinkling of non white residents who have adopted white.middle class lifestyles. That however is nowhere near the same as living in a predominately immigrant area where the culture is predominately based on the original country.
