It's a good place to start Eljay. It's often easier to notice through others what is racist and what isn't in thoughts, actions, jokes. From that you can take it a step further and be able to recognize what is wrong in the culture and society at large. remember, sometimes it' hardest to catch yourself at the prejudice games. My take on Afrikaaners is that they are a very varied bunch when it comes to how they feel about other races and what happened under apartheid, just like any other group of people is varied and has tolerant and intolerant people. To not see that is to fall prey to the same type of thinking that made Apartheid and other forms of bigotry possible in the first place.
I hope that you can find away to transform your awareness into a respect for yourself and otheres, Eljay. I have a feeling that you can do a lot of good for yourself and the wold when you do. Huggs!
