My parents were both racists ... not obvious ones (They didn't yell or picket or anything) but where and how they were raised (New Jersey) skin color defined their outlook on life. They were Irish and Roman Catholics. All of their friends and family members were the same. I'm one of seven children they had (Vatican Roulette you know) and if any of my siblings or their spouses are racist, it is in secret. I can only verify my, my wife's, and our children's definite lack of racism. Of those I'm certain ... we have all discussed it frequently. I am not sure why this is but, at least in part, my outlook in every aspect of my life has been determined by having served a career in the Navy with people of ALL races. I think the scientific definition of humans might be compared to other species. For example there are many breeds of dogs or of horses but in each case just one species with various breeds. There are zero different species, only one.
