Frankly, you’re clueless. They are protesting police brutality and racism, not the anthem. And you’ll never get it, apparently, no matter how many times it’s explained to you. If you think they’re being disrespectful to the anthem, whatever, but at least that’s an opinion. Your belief that they are protesting the anthem itself is just plain dumb.
They are protesting police brutality and racism by protesting the anthem.
If you want to think I am clueless and dumb for standing by my country, its flag and its anthem, kiss my ass.
