I think so much hinges on how they articulate the WHY behind their protest. Kaepernick came off as a highschool freshman who read one Malcolm X book and all of a sudden thought he was the smartest man in the room. His quote after his initial protest:
"I am not going to stand up to show pride in a flag for a country that oppresses black people and people of color," Kaepernick told NFL Media in an exclusive interview after the game. "To me, this is bigger than football and it would be selfish on my part to look the other way. There are bodies in the street and people getting paid leave and getting away with murder."
That was a pretty inflammatory statement demonstrating a complete lack of appreciation for the nuance of the situation.
I have heard other players explain their protests by stating that they love this country and the flag, but they are protesting as a way to draw awareness to social injustice. It is much easier for me, personally, to sympathize with the protest when explained that way.
Quotes from the players:
"There's a lot of racial and social injustices in the world that are going on right now," rookie safety Jabrill Peppers said after the Browns' second win in two preseason games. "We just decided to take a knee and pray for the people who have been affected and just pray for the world in general."
Players said linebacker Christian Kirksey led the prayer.
"We did it out of respect," Kirksey said. "No disrespect for anyone, we just felt like it was the right time and the need to do it."
"We were not trying to disrespect the flag or be a distraction to the team, but as men we thought we had the right to stand up for what we believed in, and we demonstrated that," Peppers said.
From article on ESPN. Kirksey is a leader on that team and in his community. I have nothing but respect for how they carried this out.
