Thank you for your thoughtful response... I agree that anyone who is insecure can get jealous or envious... for instance, family members.
But in relation to white women in particular, it's a systemic enculturation whereby they feel entitled to more, whether that is intangible social goods, like status and popularity, or material things... so when a person of colour, outshines them, it really challenges their ego and sense of selfhood. And so we people of colour, get all manner of aggressions.
I hope you can continue this theme by sharing some more of your experiences, as a story.
All the best.
