But on Tuesday, a group of veterans started to show their support for the 49ers quarterback.
While we're unable to verify who is a veteran and who isn't, the hashtag #VeteransForKaepernick became a top trend on Twitter on Tuesday.
The first tweet actually came from Wink Westwood, a Black Lives Matter supporter, on August 28th:
It started to pick up steam on Tuesday.
Taking a bit of a risk to speak out, active duty members used the trend to voice their support:
And some called Kaepernick a hero for what he did:
One pointed out how choosing to defend this nation means protecting everyone's rights equally:
And even used Black Lives Matter in their tweets while expressing their support:
Others said they didn't sign up to fight for a song:
And they feel like police brutality isn't being talked about like it should:
To emphasize his stance, this veteran brought up Rosa Parks sitting down:
Yet, there are some calling it a public relations stunt:
And then there was this reminder that they signed up to protect the right to criticize, too:
One guy even claimed that there is some stolen valor going on with those saying they're veterans for Kaepernick:
And some veterans aren't fans of it:
Meanwhile, Kaepernick plans to continue to sit down during the National Anthem, a decision that a lot of Americans aren't taking lightly. The San Francisco 49ers' next game, against the San Diego Chargers, will feature an annual Salute to the Military presentation.
