The Whites endured a horrendous start to the Championship campaign as QPR ran out 3-0 winners in West London at the weekend.
It took only four minutes for Leeds to concede when Nedum Onuoha, with help from new goalkeeper Rob Green, opened the scoring, before second-half goals from Tjarron Chery and Sebastien Poulter wrapped up th victory.
The Leeds players approached and appluded the visiting fans at full-time but the group were reportedly met with chants of 'what the f*****g hell was that?', according to Yorkshire Evening Post journalist Phil Hay.
Asked about the reception his players got at the final whistle, Monk said to LUTV: "It's part of the game. Our away and home support is tremendous so you're always disappointed, especially with the result we had. It wasn't the result we wanted so that disappointment comes with the territory."
It did seem like an over-the-top reaction given that it was their first game of the season. Asked if he felt it was "overreaction" by Leeds fans, Monk added: "It's football. It's what it is. Everyone's entitled to their opinion and you have to respect that opinion."
Monk's side will be hoping to bounce back when they visit Uwe Rosler's Fleetwood Town in a first-round League Cup clash at Highbury on Wednesday night.
After that, Leeds gear up for the visit of Birmingham City as the former Swansea boss aims to open his account as Whites boss in a Championship game.
