Yes, there ARE people on both sides, though, as this article describes, a strong majority of those boycotting is doing so because of the classless national anthem protests, not because Colin Kaepernick isn’t being awarded a job, and I suspect that will be even more true after this past weekend of mass protests.

Another good reason for the boycott, and one that I am using to boycott the NFL is the concussion/CTE problem.

That’s a very different issue, and I think it’s totally fair to boycott them for this.
