I’m a Titans fan and proud American (though a bit less so since we have people who actually elected the idiot in chief in our country) and veteran. I respect the principles the flag and anthem represent so I support the players right to knee during the anthem.
As far as protests go, kneeling is a pretty tame one. They’re not burning flags or wiping their ass with the flag or pissing on it or anything else. They’re quietly and peacefully kneeling.
