No, they just face race related issues, whilst white people don't face such pressures - it'd wouldn't be a black supremacy organisation, just one which desires parity. In the same way it's great there are organisations such as Stonewall which are there for gays/gay rights... whilst it's not ridiculous there isn't a straight person society, as straight people don't face the special pressures gays do, in the realm in which Stonewall operates.
The very problem is that gays have less rights, and are massively, massively more discriminated against than Black people, why gay people want to get married, an arbitrary and idea based in religion just because they want to be equal(I want equality, but I can't be bothered to fight for the equality to do something completely stupid, I wouldn't fight to join the KKK, nor a religious cult, nor a practice that is seen worldwide as a religious ceremony).
So we have gay rights groups to fight for gay rights, black people in the UK, have those rights already, they are now fighting for rights above and beyond that which everyone else has, that isn't equality, its simply people who have long been parts of groups fighting for equality, who got equality, and want to keep that power by generating new things to fight for.
Look at feminists, they still are genuinely treated worse in terms of pay, but not rights, but you have all these power feminists who don't want to give up the power they've had in their communities for decades, so the fight goes on well past equality to lots of stupid area's.
Black people in football are putting up with abuse, nothing more or less, like every other footballer, and manager, black or white, out there.
When exactly was the last black footballer assaulted by a fan on a pitch, I can't remember it, I'm sure it happened. The behaviour of football fans in general is pretty appaulling, there are groups of really quite awful people in most crowds and something should be done about it.
But ultimately are black footballers on the pitch being abused ONLY because they are black? Really, because EVERY footballer is abused, being black is merely a lable with which to attack them over. If every single footballer is being abused, and every single black footballer is abused at games for everything under the sun apart from being black, then is the problem abuse, or racism.
Real "racism" would be no abuse on the pitch except for abusing the black players exclusively, that would need massive instant huge intervention. Black footballers don't have to deal with abuse no one else gets, they all put up with abuse, they merely put up with different words used in SOME of that abuse, but every footballer can say the same based on their looks, be it ginger hair, being overweight, slow, lanky, short, etc, etc, etc.
So yeah, all players put up with the same pressure as black players.
If a black footballer couldn't get into a team, or was treated badly by his manager purely because of his colour, that is racism, that is something to fight, and something that really hasn't happened in English football for decades now. When Sagna is given 1/4 of the wage Jenkinson makes, or Arsenal refuse to hire black people, that is an issue.
Fan throws coin at white player, meh, when fan comes on pitch and attacks white player, meh, when someone yells the word black at a black player, its instantly massively worse.....
As with over zealous feminists, over zealous black rights groups are blurring the lines between racism and anything else to try and have a cause to fight.
