I'll save discussions about Ceasar Milan and his position on when to use negative reinforcement for an other thread.
And yes, I do recognize that wearing blue is not the same thing as constructive critism. I was merely refering to your assertion in an earlier post that equated wearing blue with being critical. I think we can take this point off the table.
Finally, is wearing blue the same thing as booing? I suppose it comes as no surprise that I would disagree with you on that point.
Personally I refrain from booing. I did wear blue under my CU Black and Gold hawaiian shirt on Saturday at the Alumni watch party down here in Texas. It was a symbol of disatisfaction that fell far short of being nasty.
At the end of they day, I respect people's personal choices to boo or wear blue because both are honest forms of expression.
Is there a better way to voice fan frustration about how our Colorado Buffaloes have fallen into the basement of D1 football than CU Blue? Although it's not a perfect option, it's the best one I've seen.
