On the other hand, there's more going on than what's being told publicly. Perhaps racism does play a role in this. The use of the word "uncomfortable" without clear explanation suggests this is more than just "we don't want another reflection flame war".
It's possible that this person was just hoping to use the keynote speaker as a token of inclusiveness, but I have to wonder if there isn't more going on if racism is brought up after incredible vague notions of people feeling "uncomfortable" being given as a reason why they keynote speaker got demoted to a normal speaker either.
I'm hoping the remaining leadership owns up to their mistake, put out a detailed reason why the purely technical topic of reflection is making them so uncomfortable, and lay out proper measures to prevent this from happening again, with the necessary correctional measures applied to the leadership member who went behind the others' backs on changing the invitation. They'd also need to come up with a clear and honest apology, of course.
If they can't give a decent objective reason why they're so "uncomfortable", or don't get real professional real fast, there's much more drama to be had the coming weeks.
And where do you live that inequities have never existed?
not because there is no racism in the country and neither because everyone is racistic but because the situation in general is very very different
