The point of the post wasn't that every Ute fan mocks Mormons. The post was questioning why that 40% or whatever of the Ute fanbase are Mormon are apparently ok with the disrespect served up by the minority of those who love to use athletic events as a forum for intimidating and publicly berating those who believe in a different manner.
Since you bring up the word "consistently," that question has been consistently asked by BYU fans for years and I don't see an answer in sight. When the poster said "consistently," I took that to mean that there seems to be a few or a minority that try to confront or provoke a fight at every event. Every event = consistent, not every person = consistent. And that generalization has been my 15 year experience as well.
