Racism will exist until we all stop talking about it and see people as just people. It's a cancer of the mind. Most of us irregardless of minor slips due to this mind fault see people as individuals not groups. We like some, dislike others period. For a very small group, stirring stuff up seems to benefit them in some negative way and those few, sometimes boisterous, will always be with us. In a multi-cultural world, the stranger is not a threat, just someone we have yet to know IMHO.
