Re: "...Again if the majority in a group is evil then I can assume that an individual negro is evil as well..."
You of course are free to assume whatever you choose, but your statement reflects a skewed irrationality.
If a group such as Nation of Islam is evil (and it is indeed), it would be quite reasonable to expect an individual Negro who is either a member of that group, or has expressed their sympathies with that group to be also evil.
An individual Negro which by their dress or their actions has given no indications whatsoever that they are of evil inclinations, should be judged as an individual on their own merits or detractions.
Allan Keyes and other Negro luminaries are by no means evil; nor are they enemies of the Jewish People.
Please rethink your position.
There are indeed good and bad, righteous and evil, among all races of people.
