'It's Disgusting': NFL Fans React to Anthem Protests

The "Star-Spangled Banner" was not protested by members of the NASCAR community during their Cup series race outside Concord, N.H. this weekend.

Part of the explanation may come from the strict warning several team owners gave in the wake of both comments by President Trump and exhibitions by NFL players.

NASCAR icon Richard Petty, a former driver and current team owner, told the AP that he wouldn't accept any protest of our nation's colors.

"Anybody that won't stand up for the anthem ought to be out of the country," he said. "Period."

Additionally, longtime owner Richard Childress said that any driver or crew member protest will "get [them] a ride on a Greyhound bus."

"Anybody that works for me should respect the country we live in. So many people gave our lives for it. This is America," Childress said.

An executive at Team Penske told USA Today that they currently have "no policy" on the issue because it has never come up for them.

To this day, most NASCAR races still start with an invocation from a local preacher, a rendition of the "Star-Spangled Banner" and often a flyover from a local military installation.

However, fans are often unafraid to show their opinion of drivers or politicians during introductions, as Gov. Terry McAuliffe (D-Va.) was audibly booed by many fans at the recent night race at Richmond.

Both Petty and NASCAR CEO Brian France endorsed Trump in 2016.
