Also there are hadiths regarding black people as being very sinful...
Anyway, Love which is preached by Jesus Christ our Lord and Saviour superceedes everything. Anyone wanted to cleanse or separate pepole by race or anything else as a matter of fact, is not going by their own doctrine given to them by their Lord which walked about the earth many years later.
Whichever religion we're talking about in where they talk about love of all man-kind, if you are not following that..then you are not really following your religion. However, there are some times in which others, knowing that you are bind to your belief, will cross your line....
