Apparently according to her slippery logic white people are the only people capable (or culpable) of being racist.   So when a darker black person ridicules a less (dark) black person that is not racism.  When a Mandarin ridicules a Cantonese that is not racism or bigotry.....nope just the white man......   I respect these university kids still have growing brains and they are absorbing lots which is great....but presently they are still pretty wet behind the ears.    But hey, just the white man is racist.   Does she know our Indigenous brother and sisters used to keep slaves?  Formed nations to protect themselves from each other as well (ex. Iroquois vs. Algonquin)?
