Portsmouth manager Harry Redknapp has given Sol Campbell his backing after the defender called for abuse towards footballers and managers to end.
Campbell was taunted by Spurs fans on Saturday and Redknapp has also recently come under fire from supporters.
"How can we stop it?" said Redknapp. "How can we legislate for grown men shouting things like that at Sol?
"People say they pay and are entitled to... but it's vile and unacceptable and I've got no time for it at all."
Redknapp, Manchester United boss Sir Alex Ferguson and Chelsea manager Avram Grant have all complained about crowd behaviour this season.
"Verbal abuse - I've had it, but nothing that would make me go crazy"
Campbell rang the BBC himself on Wednesday, saying the Football Association should act, but Redknapp says he cannot see how the situation can improve.
"Stamping it out will be difficult," he added. "It didn't really happen when I used to go to matches as a young lad with my dad but now it is happening more and more.
"It looks like it is creeping well into the game - even if through a minority - but it is completely out of order.
"My first experience of it was a few years ago when I was watching Ronny Rosenthal play and they were shouting shocking things at him about being Jewish.
"But some other things that are said these days are just as bad and I wouldn't even want to tell my wife what is being said now - let alone little kids hearing it.
"What chance have they got for the future when their parents behave this way?"
606: DEBATE
Tottenham striker Robbie Keane believes footballers should not be too sensitive over verbal abuse from fans.
But Keane told BBC Radio 5 Live: "Verbal abuse - I've had it, but nothing that would make me go crazy.
"I don't know what has been said to Sol. It obviously must have been something that really upset him for him to ask the FA to intervene."
Keane also defended players who swear on the pitch, insisting it is not meant to offend anyone.
"The fans are not giving abuse to ridicule you, they are saying it out of frustration," he stated.
"It's the same for a player on the pitch. If a bad decision goes against you, you say something out of frustration in those few seconds.
"We all do it. We are not doing it to upset anyone."
