QPR manager Mark Hughes says eradicating racism will be difficult.
QPR manager Mark Hughes has warned it will be almost impossible to completely rid football of racism.
More than 30 players from eight Premier League clubs chose not to support the annual Kick It Out campaign over the weekend by refusing to wear a T-shirt.
Among them was QPR defender Anton Ferdinand, who was racially abused by Chelsea captain John Terry last season.
Hughes said: "It's very difficult to eradicate totally. Let's hope that will happen but we will be a lot greyer."
Who chose not to wear Kick It Out T-shirt? Everton: Victor Anichebe, Sylvain Distin, Steven Pienaar QPR: Anton Ferdinand, Djibril Cisse, Shaun Wright-Phillips, Nedum Onouha and Junior Hoilett Man City: Micah Richards, Joleon Lescott Man Utd: Rio Ferdinand Reading: Jason Roberts Stoke: Kenwyne Jones Swansea: All players Wigan: All players
Ferdinand was joined by team-mates Djibril Cisse, Shaun Wright-Phillips, Nedum Onouha and Junior Hoilett in making his protest at the perceived lack of action about racism during the warm-up before Sunday's 1-1 draw Everton - three visiting players, Victor Anichebe, Sylvain Distin and Steven Pienaar also chose not to wear the T-shirts.
"My understanding at the beginning of the week was that everyone was going to comply," said Hughes.
"But a lot of people have made stands and possibly some of our guys felt that they needed to stand shoulder to shoulder which I think you have to accept. "Any campaign that looks to address an ill in our game and in society needs to be supported irrespective of the fact of whether they are doing enough or not.
"[Some] players feel it's time to make a stand and try and affect the authorities in terms of what they're doing and if it does that and they are better in fighting racism in sport then it's a good thing."
Everton manager David Moyes backed his trio of players although he conceded he did not necessarily agree with them.
"I spoke to the players and they decided it was their decision," Moyes said.
"I listened to their reasons and I told them my reasons why I thought they should [back the campaign by wearing a T-shirt] but ultimately it's one of these things. They have to make that decision."
