Do you think Colin Kaepernick is being blackballed?

Sorry if this has been posted I only lurk in spurts of boredom. 
If you haven't been following along with his "story" or even heard about it. He still hasn't been signed to a NFL Team since his peaceful prostest by kneeling during the National Anthem.  Some are feeling it's because he "disrespected our vets" and "great that the owners don't wanted to be associated with him" 
What are your thoughts.
