My thinking here is this.
Firstly, Butker was asked to give an honorary speech at a private Christian university, a university that espouses a faith quite similar or identical to Butker's himself.
It was on his own dime, in his own time. It was a speech given nearly a week prior to anyone in media even catching onto the fact he gave a speech anywhere at all about anything.
Whereas Kapernick did it at the start of the game literally on the time and the dime of the NFL.
As for me, I have no idea why anyone at all at the NFL would disavow what was said in a player's private time amongst their own faith community, but not disavow what is done on the field during a game when it expresses hatred for the very people that provided him the opportunities in life he was clearly blessed with.
And then, if the NFL is criticizing publicly what a player said in private amongst their own faith communities, why then aren't they publicly critical of the criminality found among their other players, since their private lives are open to public scrutiny by the NFL?
Oh that's right, it's just heterosexual white Christian men who are openly hated and harassed these days.
Maybe, just maybe, the NFL leadership could use some Christianity in their lives, and I don't know, just allow their players to have private lives without their input.
All my young life my dad worked for a Jewish man and his family. He never once felt the need to comment on the fact we had a different faith from him - and we were close.
