The short list of celebrities speaking out against the protest movement Colin Kaepernick is spearheading unfortunately just got a little longer.

As reported, over the weekend, former rap-rocker Kid Rock felt so strongly about Kaepernick’s decision to not participate in standing for the national anthem that he decided to stop his show to share with the crowd exactly how he feels.

During his show at Fenway Park in Boston, Kid Rock paused mid-song to shout, “Man, f**k Colin Kaepernick!”

While he didn’t elaborate much further during his performance on why he feels the way he does, the rock musician’s to-the-point vulgarity was met with an onslaught of cheers from the audience.

The person who captured this moment on video also can be seen putting their hands in the air and flashing a peace sign.

Kid Rock’s expletive against Colin Kaepernick came right before the first games of the NFL season, during which the football player did not stop his protest against social injustice.
