Could a white person try to enter, get turned away and sue??  Lol.

Am I placing inappropriate emphasis on a word and reading the title wrong??

Nope it is actually a tournament only for blacks.  I'm genuinely flabbergasted but I guess it's no different in principal to Black Police Associations or whatever.

Hey wait a second.... Phil Ivy isn't playing? That's just wrong. Someone call Sharpton or Jackson... 

Any whiteys playing??

My point was less about why they had the tournament and more about them being allowed to get away with it??
This isn't an event opening up competitive poker to the average black person who chooses not to play in the "predominantly white" events of which you speak.  This appears to be an event for celebrities who all have money and could easily pony up the entry fee to even the World Series which I think is something like $10K.
I must confess to not knowing who a few of them are (that's what the link is, a listing of players) but some are well known actors/comediens etc who are all loaded I'm very sure so why not call it Celebrity Poker and due to the fact that it's on the channel it's on, have the players that they have = no issue from me mostly because I probably wouldn't see it I guess.
I just don't get the hypocrisy;  You simply wouldn't be allowed (by activists and perhaps law makers) to start a channel called White Entertainment Television and put on a White Poker Stars event, all hell would break loose...so what's the difference here?
No one is barred from poker events unless by age I think yet BET appear to have barred people from this based on the colour of their skin. 
This event could easily have been held with the same competitors any number of ways but giving it the name they did, I think, makes it harder to advance the race issues that that country and many others, are still experiencing.
Anyhoo.

Offensive??  Definitely wouldn't go that far but it's the nomenclature that I'm having issue with, yes.  As I've explained, exchange the word 'black' for 'white' in the channel and the tournament and all hell breaks loose and I'm at a loss to see the difference.
BET has been around for ages, I get that, there are Black Police Associations, Pakistani Societies, Women's Guilds, Freemasons etc etc etc all exclusive by their very nature, I get it all, but this is a game of chance and skill we're talking about and I'm not feeling the need for the overt inclusion of one race only.
I also understand that I appear to be in the vast minority of people who even give 2 shiney shytes!!   Must be a whitey complex or something.

In answer to your addition, yes I think I would although some of your examples are accomodated in so much as some tournaments or whatever require that you are a legal resident of a country.  A good parallel I guess would be a Protestant Poker Tournament being held in Dublin.  It flies in the face of the biggest struggle in that region.

"all television was pretty much WHITE ENTERTAINMENT TELEVISION... "

Kind of reminds me of when I asked my parents why there was a Mother's Day and a Father's Day, but no 'kids day'?   "EVERY DAY IS KIDS DAY!!!"
