Rocker Ted Nugent says the Florida students calling for gun control have "no soul" and are "mushy-brained children".
He made the comments on Friday while defending the National Rifle Association as a guest on the Joe Pags Show, a nationally syndicated conservative radio program.
Nugent, an NRA board member, said survivors of the Parkland school shooting are wrong to blame the NRA for mass shootings.

He went on to say that "the evidence is irrefutable, they have no soul" and that the gun-control measures they support amount to "spiritual suicide".
A representative for the 69-year-old Nugent did not immediately respond to a request for comment.
Meanwhile, several advertisers have dropped Fox News personality Laura Ingraham after she mocked a survivor of the Parkland shooting online.
Ingraham announced on her show late on Friday that she was taking next week off.
Eleven companies so far have pulled their ads after a pushback by Parkland student David Hogg, 17, who called for a boycott of her advertisers.
A Fox News Channel spokeswoman said Ingraham was taking a pre-planned spring vacation with her children.
Hogg took aim at the host's show, The Ingraham Angle, after she taunted him on Twitter on Wednesday, accusing him of whining about being rejected by four colleges to which he had applied.
Hogg is a survivor of the February 14 mass shooting that killed 17 people at Marjory Stoneman Douglas High School. He and other classmates have become the faces of a new youth-led movement calling for tighter restrictions on firearms.
On Thursday, Ingraham tweeted an apology which Hogg did not accept. Hogg wrote on Twitter that an apology just to mollify advertisers was insufficient.
