Count me as mostly indefferent but slightly negative after reading through the thread and hearing the various perspectives. No, there is nothing forcing anyone to participate, but yes, there will be social pressure to do so, and, depending on what else may be going on socially/culturally/politically at any given moment, it could create what is at best an unwelcoming environment for some customers and at worst something uglier. So to me, the value added by the practice isn't sufficient to overcome some of the potential negative feeling the practice could spawn.
Additionally, like I implied in the original thread, I think it's symbolically problematic that this is one of the tangible things UConn's interim AD has focused on at chaotic and critical point in college athletics. It's like Congress passing a bill making it National Brie Appreciation Day or something in the midst of a budget crisis. Although doing so may not actually prevent Congress from focusing on the budget, it doesn't send the message that it's focusing on what the country needs Congress to address. Similarly, there's the cynic who will look at this and say, "Gee, UConn may not have a seat at the grownups' table for football and other sports, we need a new practice facility, we need to look at innovative ways to promote our sports and increase attendance, and the Interim AD's big idea is...reciting the Pledge of Allegiance prior sporting events???"
But again, not an issue about which I have a ton of strong feelings.
