Many people don't believe the military protects our freedom, and many don't believe law enforcement serves and protects the people. Many believe instead that these intitutions have mutated into self-protecting, self-perpetuating enterprises. Interestingly our Founders didn't even want a "standing army" and remarked often at how the British Navy only looted and abused the British people on behalf of mercantilist traders who coveted foreign raw materials and export markets for British goods.Sorry, I don't remember any of the LGBT's ARMY, NAVY, AF, MARINES fighting/dying in wars to ensure America's level of freedom. Don't see the analogous comparison.
The comparison I drew was how the Right now supports a professional athlete peacefully declining to participate in league-sponsored ceremonial support of a cultural ideal. However the Right was quick to deride NFL players who also felt inclined to peacefully not participate in league-sponsored ceremonies.
