Good luck with your presentation -
But I think it's about time that new (and old) SF members stop wasting their time with these kinds of threads.
I - for one - will stop taking the bait.
The answer should be, to questions like this one: "Search the archives."
There are numerous threads on SF that address the black vs. brown issue. There are numerous threads on AAAC that do the same.
Case closed - I hope.
