I think that fear is a very powerful factor.  And because of fear we tend to deny the reality that is absolutely transparent to someone who is viewing it without the fear.
 And I think that the whole process of denial is a very powerful one and accounts for what someone delightfully described  to me the other day as the ostrich mentality, when you put your head in the sand and the person added, of course the trouble is you leave your rump exposed.
 And I think that because of fear we have largely put our head in the sand and what concerns me and I don't know if this is underlying your question, but what concerns me today is that you can't find anyone who ever supported apartheid and there is so much denial going on that I think that those people who have never actually seen through it, could also be manipulated again.
 And to that extent I utterly share your concern and think you've raised a very important point.
