a couple of things here.....most people understand the difference between good natured ribbing/rivalry banter---this definitely fell into that category. My son is 9 and has no clue about the ugly side of the rivalry. I attended the U and had nothing but good experiences there including meeting my wife there.
Secondly, if one cannot separate religion from the sports side of the rivalry and get offended by the actions of a 9 year old, they've got issues that no message board will help. I understand that Bronco and others bring religion up a lot (and BYU sports were the primary reason for my initial interest in the Church), but those have nothing to do with playful fan interactions.
If any of you need some tissues to blot your tears, send me your address and I will send you a box of Kleenex tomorrow.
