Rob Schneider was one of millions to share their condolences following Dikembe Mutombo's death ... but his tribute to the legend stuck out in particular -- as he used the tragic news to push his anti-vax stance.
The comedian went to X to mourn Mutombo's passing on Monday ... starting it off by saying, "Rest in Peace..."
Many wish he would've just left it at that ... as the rest of his post -- which quoted a video Mutombo made in 2021 to promote the Covid vaccine -- speculated if getting the jab had anything to do with the former All-Star's death.
