“Voice suppression”? I don’t know WTH that means—not being allowed to SING the National Anthem??? I guess you mean the players should be able to EXPRESS their 19-20 year old brainy thoughts anywhere or anyplace. They’re kids. They get their impulses from social media and join the latest mass mentality. Deep, philosophical principles? Sure.
I don’t give a flip what they do, say or think on their own time—-but, when they don the university’s uniform, on the university’s property, playing in a university’s sponsored game and in front of the university‘s supporters, they must REPRESENT the university, selflessly, rather than demonstrate their private and (I’m sure) “thoroughly fleshed-out” philosophies. And, yes, I AM the old man who doesn’t want kids playing on his front lawn riding Little Tykes toys.
