Because it "disrespects the veterans" in some people's eyes. Astonishing, isn't it, that the same people who found issue with Kaepernick's protest probably have never heard the name "Nate Boyer"[1] before-who is both a veteran of the armed forces, and a veteran of the NFL.

It's never good enough.

I’m pretty sure “disrespects the flag” is little more than a strawman to attack instead of them having to discuss the actual point trying to be made.

And painting a blue line down the middle of it is the best way to respect the flag. /s

Of course it is.
