I think at this point there is not much more to be said in terms of the subject of the thread.
MN has made its stance clear. It is up to us what to do next.
I am not going to waste my time now arguing with the racism, trying to point out facts etc. It is pointless trying to reason with hatred.
I will report though. Although I am a bit disturbed about some of the posts that have been allowed to remain, so not certain how much mileage there is on that.
Personally, I am on the fence now about staying here (yes I know who cares, airports etc). But maybe the racism will die down.
Eta: if a person can't recognise any race hate in the three thread examples, then I refer them to my third paragraph. I also suggest they read the post by nauticluscat.
