This has nothing to do with the subject and everything at the same time. But first a few ground rules.
The pledge is not a religious activity.
The words, "under God" were not part of the original pledge. They were added by the same people who would have been in Salem or around during the Inquisition. Looking to establish their views as the benchmark for legitimacy.
The idea of pledging allegiance with zero consequences, requirements or means of validation is the moronic puffery it appears to be. I mean I made my pledges daily as a kid, am I good? What's the expiration date? Can I renegotiate?
Now to the point, this look at me aren't I a great American because I drone though these words before the local PTA meeting is simply an exercise of power by the person putting it on the agenda. It has no bearing on the business of the day. Just like your religion has no bearing on the football field.
If a coach wants the teach the values of sacrifice, togetherness, respect, humility, etc. He can do so without bringing the icons and dogma of his particular faith into the discussion. This is what KO does and I assume Geno and Diaco.
Guys like Swinney, simply lack the vocabulary and imagination to use different words and keep Sunday Mass out of the locker room. It's not all that difficult a concept. People who think it's anti-religion or anti-Christian are missing the point. In America, a captive audience shouldn't be subjected to the personal religious tenets and rituals by authority figures. Nor should it be required directly or indirectly as a condition of participation. The First Amendment protects us from that kind of thing.
