Your argument is...what's the expression...piss poor, and strikes me as more political than well-reasoned. And here is why:
While it is undoubtedly true that Mike Gundy has the freedom to express whatsoever he chooses to--including on this clothing, his bumper stickers, at press conferences, etc--his actions do not exist in a bubble that is automatically free from rebuke.
No person has to placate him one bit.
So yes, he can wear an OAN T-Shirt and feign ignorance and shock--absolute SHOCK he tells us--at learning OAN's position on BLM (because, of course, they hide their viewpoints so well), but so too, is Hubbard empowered to speak out against this, or to refuse to play for him.
That, too, is expression. And it has every equal footing with Gundy's T-shirt selection.
I mean, you agree that Hubbard has a right to free expression, too, right? So why do you mislead by stating that Hubbard is "trying to tell us what we can and can't say"? He is doing nothing of the sort. Rather, he is using his own statements and actions to comment on his head coach's decision.
And that, dear FeralFelidae, is a most American thing to do.
