Colin Kaepernick’s national anthem protest has made him a lightning-rod for criticism, but that doesn’t have him fearing his safety when the 49ers visit the San Diego Chargers for Thursday’s exhibition-season finale.

“No, because if something happened, you’d be proving my point,” Kaepernick said Tuesday in an informal talk with reporters at his locker.

To draw attention to racial injustice and social issues, Kaepernick has sat for every national anthem through three exhibition games, though his protest didn’t become known publicly until after Friday’s home loss to the Green Bay Packers.

“I knew what I was walking into,” Kaepernick added. “That’s why it’s a sacrifice.”

Kaepernick’s safety, and that of his 49ers teammates, will be handled not only through the Chargers’ stadium personnel but also the 49ers’ own detail that typically travels and takes a pro-active approach in such matters. A 49ers spokesman declined to detail any such plans.

Coach Chip Kelly said Kaepernick indeed will play Thursday, and that presumably will be in a starting role. Blaine Gabbert, their starter the first three exhibitions, will not play. “We’ve got a good understanding of where Blaine is,” said Kelly, noting that Kaepernick missed the first two exhibitions with a sore arm and needs more snaps for evaluation purposes.

San Diego’s massive presence of military personnel could result in a rude welcome for Kaepernick, who’s insisted that his anthem protest and anti-flag comments are not meant to offend the military. The Chargers are expected to hold their 28th annual “Salute to Service” at the game.

“I have great respect for our men and women that fought for this country,” Kaepernick said Sunday. “I have family, I have friends that have fought for this country. And they fight for freedom. They fight for liberty and justice, for everyone. And that’s not happening.”

Kaepernick said the only articles he’s read are ones filtered to him through his family and close friends. Although he’s drawn support from many realms, he said he hasn’t directly heard from the White House, and that his phone hasn’t been overloaded by messages because few people have his number.

Wide receiver Torrey Smith is expecting a barrage of taunts toward Kaepernick from the San Diego crowd.

“You’re going to get dog-cussed, and people have the right to do that,” Smith said. “Kap knows what kind of heat he’s going to take. … You’ll hear stuff and see signs.

“If people are offended by (Kaepernick’s protest), that’s part of the problem. But people shouldn’t get physical over it.”

Outside linebacker Corey Lemonier said he has friends in the military based in San Diego. Might they sound off on Kaepernick? “Yeah, but that’s what it’s about, the First Amendment,” Lemonier said. “Everyone has a right to say what they want to say.”

Because this is the exhibition finale, players such as Lemonier won’t be focused on their safety as much as this being a last chance to prove their roster worth. “It’s pretty crucial for me and most guys, and I can’t be focused on (safety),” Lemonier added.

Asked if Kaepernick will require extra security on the 49ers sideline, Kelly responded: “I’m not a security guy.”
