Well, as I studied sociology once and my special interest was racism (the word has another meaning in this context than used normally and can be replaced with any other category of social determination like religion or age or anything), I tend not to discuss topics like this often. It is more complex than I had believed in the beginning.
I can fully agree to your opinion as a part of a really interesting and complex conglomerate of cognitions. Unfortunately, this list isn't the best place for this discussion and to be honest I wouldn't like to start a scientific dispute in English language as my poor language skills wouldn't suffice.
Thanks for the correction, best regards, Richard
