whether another forum exists or not does not matter. What matters is that El Jefe has built a forum that is not restricted to BYU athletics and topics related to BYU athletics. The forum covers a wide variety of subjects, including University of Utah athletics at times. Those subjects are not forbidden and I would suggest that any subject which drives participation in a discussion, thus increases hits, would be encouraged by the owner of this website.
El jefe has also given you many tools that let you restrict what you see. If subjects like Utah football offend you then you can take the necessary steps to limit it from your view. Or you can make yourself look foolish by insisting that your opinion of how the board is to be run should trump what is actually unfolding before your eyes... a long discussion thread on a topic you say doesn't belong here.
This "you don't belong here" tripe is old and tired. It has been hashed and rehashed. If memory serves, which often it does not in my case, it has been hashed and rehashed by you. If it is really that bothersome use the tools El Jefe has given you. Fire up some ignores and block some categories.
