It appears to me you take the position that you are correct, and that any challenge is necessarily one coming from a position of ignorance or malice. I invite you to re-think your approach to this sort of conversation.
Always, and always open to reconsidering my position or approach.
> (e.g. that I have not done reading on this subject)
You're not demonstrating familiarity with the subject. Your questions have come from a perspective that is addressed in the subject matter.
> or that you are making personal accusations (e.g. that I may not recognize advantages)
That wasn't an accusation. It was a fig leaf. Your positions have rejected your advantages as a white person. "You're off the mark. Way off."
> That perhaps my interest isn’t in fighting but merely challenging your assertion and assumptions?
Your interest increasingly seems to be defensive.
Edit:
> I invite you to re-think your approach to this sort of conversation.
Thank you, but no thank you. You don't seem to be interested in actually discussing the topic, or reconsidering your own positions. I'm 99% certain that I won't make any headway with you regardless of my approach.
