Wladimir Klitschko -- Tyson Fury Is Raging Sexist Homophobe ... 'F*** YOU'

Wladimir Klitschko just told boxing superstar Tyson Fury to go F HIMSELF -- trashing Fury over recent homophobic and sexist comments ... and saying he disrespected Elton John.

Klitschko was doing a media event in England to promote his rematch with Fury -- he blasted the boxer ... saying the sport needs a champion it can respect, not a bigot like Fury.

"What comes out of Fury's mouth ... disrespectful," Klitschko said ... before summing up the comments Fury spewed out of his mouth in 2015.

"That all homosexual men and women and pedophiles belong in the same place, jail ... that women belong in the kitchen and on their back."

"So, that's basically where [Fury] sees Elton John and The Queen."

Then Klitschko delivered this message -- "To people that say and think the same way out there ... and to you, Fury ... I want to say, 'F*** OFF!'"

For his part, Fury insists he's not a homophobe or sexist. But Klitschko just ain't buyin' it.
