I do'nt understand why SOME disruptions of the national anthem are cool, and some are trashy/selfish.
Kneeling? Unpatriotic.
Sitting? Anti-American.
Locking arms? Classy.
No matter what, if you're a pro athlete, and your behavior is intended to disrupt and distract from the national anthem - so you can push your cause - then you're usurping the national anthem and you suck.
Seahawks, Cap, Dolphins... they can all eat a cawk.
