I have never claimed that, but you keep propping up that Straw Man.
And, yes, while it is not been explicitly stated, on some level, it does seems implicit in the arguments by the anti-Kaep crowd. If one is saying that he shouldn't be doing it even though he has the right, and should be punished for doing it, then it is not much a leap to say that it should be prohibited by law. And when there are calls for him to lose his job, blackballed from the NFL, be publically shamed and asked to leave the country, it doesn't seem to show much respect for his right to silently protest by kneeling during the anthem.
And if everyone agreed with me that he has the right to do this, then what is all the excitement about? If that was the point of view, then everyone should have just shrugged it off and there wouldn't have been a controversy, nor a thread about it in this forum.
